Long Ram 413 DYNO Tested! - Historic Chrysler Engine 

This wasn't an "Engine Dyno Session" this was an "Engine Dyno Art Class" . Just fantastic to watch, many thanks.

Thanks Nick for having your nephew involved. Our love for these classics will die if the next generation doesnt follow in our footsteps!!

What an engine! You have to remember what was out there in 1963. This thing was so far ahead of its time. You can barely tell it's running at idle. What superb balance. Chrysler 300 with this engine was the ultimate 'sleeper.'

I can't remember ANYBODY ever testing, tuning, or tinkering on the legendary and mysterious Chrysler cross ram engines whether in magazines, videos, television... That was great, Nick. It's very nice to see Nikko's admiration and respect for ol' Uncle Nick. Young people probably don't know how much that means to old guys like us.

Tears of pride Nick. I have that setup in my 300K. There's NOTHING like rolling the carbs open and listening to the barometric pressure come down in the immediate area, and feeling that big Chrysler start to move out just slipping the rear tires a little more than it's making way, down the road.

I enjoyed the nostalgia of seeing the 413 long ram on the dyno. As I commented on the 413 head work video, in 1967 I drove a 1964 300K which had this same engine. The big torque curve at low and mid range made the 300K a sleeper that could terrorize unsuspecting victims. The Chrysler 300 letter series cars were known as “bankers' hot rods." Sales of the 300 letter cars plummeted when the 392 hemi was replaced by the wedge. The neck snapping acceleration of the hemi is why people bought the car - top speed was not important. The 413 and 383 could not compete with the newer Chevys and Fords. The Chrysler engineers trumped the competition in 1965 with the 440 high-deck and the 426 hemi. The increased deck height allowed the engines to rev much higher because of more hold-up time (power is rpm times torque). The 440 became very popular - it was cheaper and lighter than the hemi. The basic 426 hemi design is still the only engine used in top fuel and funny cars.

In 1961 my grandmother's car was a 300 with the 413 long ram. A terrifying car. The odd thing was that my grandmother was a terrible driver with no sense of modulation - she went down the street in a series of leaps.

Cool story. Our town has Chryslers oldest dealer. In the late fifties they ran the private Chrysler car on the flying mile at Daytona beach and the driver worked for the dealership. My friend owned a new Impala with a 409. The local police ran Pontiacs for cruisers. My friend was being chased by the police on route 30 when a Chrysler came up behind and passed the police car, passed him and the last he saw was the tail lights going over South mountain.

For a comparrison between the long ram and the 4-Barrel induction systems, you should plot the horsepower and torque for each on the same graph. The shapes of the curves and where they cross over would be interesting to see.

Love the act of Nick's Nephew offering to step up and do additional work without being asked. You dont see that kind of work ethic in a lot of younger people these days.

How fondly I remember my early teens and the days of the 406, 409, the 413 and The Beach Boys song "Shut Down"...I didn't like the looks of the early '60s Chrysler produced cars at the time, but that changed fast in the mid '60s...What a beautiful classic engine.

The 413 was an awesome engine. My buddy from school was given one by his grandfather.,in 1967,and he was told"It was made to RUN,boy,so don't dog it,..DRIVE it!" We're both 70+ now,and he still has it.

Something most people fail to understand is that the CTR, was DESIGNED for high TORQUE rather than top end horsepower. As Mario Andretti used to say: "Horsepower sells cars, but TORQUE wins races!"

Long runners good for big torque. Chrysler always had the cool looking stuff that no One else had. What a wow factor when you lift the hood. Love it

I drove a 1963 Chrysler 300J several times around 1966. My dad's friend had one and paid me to come pick it up and wash and detail it. You can imagine what a 16 year old kid did with it when no one was looking. My love for muscle in cars started with this car. It was heavy, but compared to almost anything else on the road, it had serious guts when you got on it. White car with a champagne colored leather interior. What a dream drive! This project is definitely bringing back memories.

I love how he tries everything, back to back runs, etc. by the time you drop your engine in your car you know it’s ready to drive it any way you want to and it will be just fine.

We all wish we had an Uncle like Nick. Back when engine designers didn't have restrictions they were able to produce incredible products. Now if you want more HP/TQ it's all computer related.

I was at Motorama when Donny Oake dropped off the carbs. I’ve know the Oakes , father Dave & sons Donny & Daryl for over 20 years . They are the best . 500 ft lbs is impressive. It’s the torque that moves you. That big cars needs torque. I’m sure the owner will be very happy. It’s the torque that you feel when you step on the gas. Well done !

Those old cross ram 413s were only around 375hp from the factory, but they produced TQ and HP at such a low RPM they were beasts stoplight to stoplight and on the strip, and did so with even a modest gear ratio to preserve a little top end.

I love seeing two generations of family helping and teaching each other, way to go Nick on working with family!!!

The look of satisfaction on Nick's face when the glove trick worked,priceless.

This effect of the long runners is why the slant 6 manifold is how it is. Each pair of runners is ramming at max efficiency at a certain rpm. Makes for a nice flat torque curve. Torque is where the fun is

Dynos don't lie! Just recently, Nick showed how efficient the cast iron exhaust manifolds are on a 528 Hemi! Today, the dyno speaking loud and clear, once again, with astounding torque numbers on this RB intake system! Another tribute to the Chrysler engineers! On the street, torque is king!!!

Fun rebuild. Brought back many memories. I had a 1962 300F 413 with dual cross ram manifolds. I don't remember if it was a factory feature or not, it had ram air ducts from the headlight area through mesh filters and tight onto the carbs. It was a real beast, and luxurious, all leather, diamond white, with full power seats that swiveled out, rear buckets, push button gear selector on dash, and even came with ambulance tires. Talk about torque, and horse power was awesome--I recall it was only "rated at 335hp" but you could feel the power boost with speed. And we had premium white pump!

I've been waiting for these number results for over 45 years, how exciting.

Nick, We live within hearing distance of the Chrysler Proving Grounds in Chelsea Mich. We have been hearing some engines that have the old rumble of the sixties and seventies. We are over 70 years old and have been here since 1972 and I will tell you, It thrills our hearts to hear those muscle engines again!

My grandfather had a 413 crossram in the 60's. In the late 50's he started out as a mechanic at the Dodge, Chrysler, Plymouth dealership. In the 70's, He retired as the general manager at the same dealership. He always drove the best muscle cars of the 60's and 70's. He sold my father a new all Black, 1974 Dodge Charger SE. In 1979 that Charger became my first car in high school.

when nick asked niko if he ever installed a carb I was like whoa😮 couple minutes later I realize niko knows carbs a little I hope he can carry on uncle Nick's passion...

In 1971 I was 18 years old and just like any other gear head. But we were poor for the most part. I survived! These were the only cars I could afford. I paid my own insurance and whatever else. I was always responsible. I really took care of my cars and pickups as I got older. Thanks again. Your Nephew is awesome, teach him the ropes Nick!

HOTDANG!!! A cool and overcast Texas afternoon and 90 minutes of Nick, Niko and the 413 (426) on the dyno. Better than hiding from tornados in the storm cellar like last week. Thank you Nick and George! Great video, and I’ve already shared it with my son and grandson as well as my two brothers.

This engine is basically pure factory stock specification! Stock intake, stock exhaust manifolds, stock carbs, stock heads, near stock cam profile and even stock air cleaners! And the power loss with the air cleaners is vary low! Only a couple of hp and pounds of torque. This is a great engine package for a big street car. Loved this test!

I think Chrysler put that long ram intake in a couple models, including their ultra deluxe wagon. Boulevard performance as opposed to race track speed. I think you guys nailed it.

The early years of "muscle cars" like this one and onward were magical. I'm so fortunate to have lived and enjoyed those times. I've always been a Mopar guy, owning three 440 magnums a 383 and a 340. Glad you love um too. This particular engine is one that I have always admired since I was a kid and it's looking good. Best Regards to you and Nico, your fortunate student. It's so cool that the Chrysler engineers were allowed to do inventive experimental and creative things like this.

I love the way you can see the ram tuning effect pushing fuel and air backwards and up out of the carbs as it passes through a resonance RPM (see the pull starting at 32:30). Those carbs have a tough job metering fuel across the whole band in a setup like this, but they do it. A system like the long ram would probably be best suited to a flat plane crank where the intake pulses always alternate between banks, instead of having 8-4 and 5-7 pulling from the same carb twice while the air on the other side is dead twice. The balance tube addresses that, but I’m sure it’s not ideal. Very, very cool stuff.

The J300 was my first car in 1968,I was 16. I bought it from a used car dealer for 700$. It was missing the crossram,it had a 4 barrel on a cast iron intake. I put a Holley 780 with a hit rise on it .I had a lot of fun with this car.I think I remember 0-60 in. Close to 6 seconds. I ran that thing to 6 grand all the time.Your show is great, thank you.

That is a real professional job! The motor looks as awesome as it runs! The owner will surely have the "Mopar Grin" ear to ear the first time he trips it!

My first car was a Buick GS455,that car was rated 360hp and 510 ft lbs of torque from the factory,she was always stock and pulled like there was no tomorrow..I was once told by a dragracer,torque outruns hp.

13:20 You keep an eye on him, Niko!

Hi, Nick; I owned a 60 300F with the same 413 engine with 30" runners. The engine called for 100 octane fuel which was readily available in those days. The difference between regular and premium fuel was only 3 or 4 cents a gallon. You will attain the hp number you're looking for if you use 100 octane gas. I enjoy your show.

I thank God we have you Nick to show us all on RU-vid what OLD MUSCLE CAR is, PERIOD !! YOU ROCK FELLA for sure. Nice to see a young aprentice learning and taking an interest in OLD SCHOOL STUFF !!!!

do you know what the coolest part of this video is? the look on Niko's face after he revved that monster up. a new generation of hot rodder is coming of age!

I am not a Chrysler guy, but this is my all-time favorite intake!

I watch all of Nick’s videos. I’ve waited on this one more than any other. In 1966 I rode with one of my friends Uncle in his 1964 300 K. It smoked the little bias ply tires at 85mph passing a grain truck on a little highway in NM. That car belongs to one of his nephews now. It is not running but in decent shape. He plans on restoring it. I was 12 and that car forever gave me the fever for fast cars.

Kudos to the gentleman that rebuilt and set up the carbs. Outstanding!

The long ram 413 on the dyno, it doesn't get much better than that on a Monday. I have been waiting to see what numbers the 413 makes with the dual ram intake. Here we go!!!

Absolutely beautiful Nick ! It's great to see your nephew involved, he couldn't have a better mentor. I love the way those long ram manifolds look.

Nice to see the youngster getting involved into big V8 engines. I had this experience when I was 15 years old. A friend did dirt racing and we bought then a 3 month's old, but wrecked '69 Dodge Charger R/T 383 (the only on the European continent at that time). That was my first touch onto the Mopar engines. I still love the V8 engines and I learned a lot about engines that time. Also that time I learned big diesels from and also the trucks, front loaders, draglines and kind of "fuel burning things". Teach "little Nico" as much as possible.

Another great one Nick, so glad Nicko asked if he could blip the carbs, wanted him to feel the human to machine interface and he will not likely see this setup anywhere else.

I love how humble Nick is with the apprentice Nico😊

I wondered for years how the 413’s with those long intakes could really perform!!! Sweet Torque. Thank you Nick, Nico and George! You knocked this one out of the park! 👍😃

Another great episode! I just wanna point out, that not only is George a super cameraman, but his narration in the beginning is fantastic!

Nick is worth his price in gold! As the years have gone by, fewer and fewer of mechanics have the knowledge that the old Chrysler mechanics had. These cross-ram engines were always difficult to keep in specifications but when they were they were tourque monsters. Love the videos and glad I found them.

Those kind of numbers from a factory built engine back in the day is highly impressive. 500ft pound at 3500rpm is no joke!

I love the HEMI’s, the other Mopar big blocks and small blocks, honestly, I love all engines. But seeing this legend in action on the dyno was a real treat. And seeing young Niko learning and getting excited about these beautiful old engines truly gives me hope for the future. Love the channel!

I had heard of the 413 but I never saw one. My dad’s brother worked for a Chrysler dealer as a mechanic from 1959 until the Chrysler shut down. He once owned a DeSoto, from the last year that they were manufactured. He was so proud of that car.

I’ve been waiting for this video ever since Mike dropped it off. Watching Mike and Nick that day was my first view of Nick’s Garage. I’ve been back many times, catching up on 4 years or more of great RU-vid video. Again, I can’t get enough of Nick’s Garage or this particular engine/body combination. I’ll never forget driving my Dad’s ‘63 Chrysler New Yorker with a 383. I would be doing over 80 mph when my Dad would chime in, “Watch your speed.” Actually, I was watching my speed and enjoying every minute. Such a smooth ride, so much effortless power.

That torque coming in at a lower rpm is really cool. This thing reminds me such much of my '64 New Yorker with a 413. I did some mild upgrades to it. Total sleeper.

I'm sure that Mike will be happy with the engine in his 300-J. You commented that the fuel in the '60s might be different. A 100 octane fuel from the '60s is about equivalent in octane to the Petro-Can 94 you are using, but if there is no spark knock, then the octane number will not influence power. As for energy content, which will affect power, the old fuels might have the edge, depending on how they were blended. If the '60s gasoline contained more reformate and less cat cracker gas, it would have slightly higher energy content. Nowadays, 94 is blended to contain less reformate and more iso-octane, plus some ethanol. The ethanol has less energy, but iso-octane is a near-perfect fuel. All in all, I doubt that there would be more than 5 HP from the best case to the worst case. Incidentally, most (if not all) of the iso-octane in Canada is made in Edmonton, so maybe along with the valve covers, we also sent you some horsepower from Alberta!

Nice video, Nick. Tom Hoover certainly knew what he was doing when they designed these. Way ahead of their time. Now, with fuel injection, most manufacturers utilize these set ups. They can design them in a round shape, since they only need to flow air.

I can't wait to see the face of the customer when he drives it the first time. You guys have done great, and brought the pages of the Chrysler history book to life.

That was the biggest grin when Niko gave the 413 a rev...Get you one Niko !

From what I remember, Engine Masters and Richard Holdner have run old motorhome 440s on the Dyno, even with aftermarket intakes, carbs and header and they didn't make anywhere near this power in the General Mayhem '69 Charger. This Sonoramic Commando 426ci would be a huge step up.

I love the way Nick gives his nephew permission, “Do you want me to hook it up?” “Yeah, go ahead.” It means a lot to get that kind of encouragement when you’re just starting out. Nick has such a gentle touch, considering how hard he drives himself. Just my two cents.

Glad to see you prepping the next generation, seems like a good kid willing to soak it in, and you are a very good teacher.

That is one sweet piece of history. And to see a couple of giddy, gigling grinning kids bouncing around with excitement, while Nico watches and helps with a real sense of awe. You are so lucky, Nico. I can see this has been a big day for you, as it should be. Thanks, Nick. An absolutely amazing 90 minutes.

Hey Nick, in the video with the single 4 barrel carburetor I guess you'll get at least 25lb ft of torque and at least 10hp more with the stock intake and carburetors. Well one out of two isn't bad. 😁 Being a retired motorcycle technician and machinist for mostly Japanese brands, what you did to freshen up that engine you improved the performance by milling the block .015" to get more compression and doing a better valve job including modifying the bowl area in the valve seat and port area on both intake and exhaust to increase CFM, my guess is that the torque and hp #'s that were published was high unless the fuel back then produced more power. From what I understand, fuel was much better back then except the Led in it was not good for the lungs. Awesome video Nick. 🧓👍

Back in the '60's Sunoco gas octane was rated 90(lawn mowers;93(regular);97.5(premium);102 (super premium...blue in color). It's tough using today's fuel to equal the hp. produced then.

Nick, when I was 18 years old. I bought a 1961 Chrysler New Yorker for $50.00. It had the 413, all I did was put points, condenser, plugs, rotor, cap, and wires. That engine was a monster. I had so much fun with that big boat. I even took a 68 Road Runner 4 Sd out of the hole! I couldn’t believe it either! Thanks for the memories

What a torque monster! Good to see your nephew taking an interest so you can pass on the knowledge to a new generation. Bravo Nick. Stay safe all, God Bless.

I NEVER get tired of hearing the power growl of a big block on its curve!! Awesome looking engine.

Nick is like a brain surgeon with engines, it is amazing to watch him, we don't know what is knows and what he doesn't know is smaller than what most people will ever know.

Yeah, I love to see Nick finally use the choke; it is very important to choke the air intake to get the motor started. I’ve never understood Nick’s aversion to using the choke to start the engine. But he’s the engine builder, I’m just the poor user trying to take care of my engine. 😮

I remember one of our locals ( here in southeast Texas ) who's father owned a Mopar dealership raced a 1961 Plymouth Belvedere with a 413 max wedge in the super stock automatic class at our local drag strip. What a pleasure watching and hearing him run, awesome ! Nick, you sure brought back some memories ! ! ! Thank you for that !

I really dig it . Ole school horse power from the factory. Awesome job NICK and crew😊

Every minute of this episode was awesome. Favorite moment was, Niko goosing the throttle !!! The best !!!

Gotta love it. Sound waves were used for a supercharging effect. Bravo Mopar and Nick.

Put the air cleaner base on to smooth out the air flow into the carb will pick up a few HP.

I didn't believe the old technology could keep up with new, but man, I was wrong!!! I believe the best torque numbers with the four barrel induction was arouond 460 ft/lbs! The long ram induction hit 500! Congrats to Chrysler engineers, that long ram intake is something special!!! Great job, Nick!!

Thank you Nick! You keep these classics alive! All of them, regardless of make of model. The young guys you take under your wing and teach the right way are the future of tthese great muscle cars! Thank you and thank those younger generations who love these timeless treasures!!! Nothing but love!!! ❤❤❤❤❤❤

Thank you, Nick! These are engines that are legends! Whether a 361, 383 or 413 with the same setup, they ruled the road!

I wonder what those long rams would do on a 440? Thanks for all the testing and results. Awesome engine and looks totally alien.

Shut you down with a 289 vs a 413 SS? NOT LIKELY!!!!! Describe that engine in one word? AWESOME! I remember seeing an old Hot Rod type magazine with a late 1920's or early 30's Chrysler Phaeton with a 413 Long ram engine in it - of course the sides of the hood had to be removed for the engine just to sit there - it was SO WIDE. It was one of THE COOLEST cars I have EVER seen. VERY tasteful in Cream with Brown fenders and pinstripes. And the Long-Ram engine was the pièce de résistance!

Man, was I waiting for this one!!! I figured that long ram intake would make strong torque, and it DIDN'T DISAPPOINT!!! Great job, Nick and guys!!! I know, Nick, you HAD to be proud having Nikko there with you, right in the thick of it: he looked like he was having an absolute blast!!! Great stuff, and George, FANTASTIC production skills!!! Manny was right on with his description of how those long runners produce that supercharging effect at the lower rpm band. KUDOS, NICK!!!

Great job guys. Chrysler was ahead of the game with their engineers!!

The reversion / fuel standoff over the carbs is cool looking

I noticed when I could see the bottom of the carbs that the primaries are smaller than the secondaries. That would make sense for fuel mileage when you have both carbs opening at the same time. Great job by Nick & Co. those torque numbers were not seen until the big GM 455 engines of the '69-70's.

Wow what a wonderful engine Nick, and good on young Nico for learning the ropes. We need young men like him coming through to look after our old Mopars. Greg, New Zealand.

God bless you Nick, for teaching the younger generations about these wonderful engines and cars. Love the Videos keep up the good work.

Hats off to those Chrysler engineers. Wow!

Man seeing Nico learning from Nick takes me back to when I was learning rotary's from my late father. He had two loves when it came to engines, old school Mopar's and Mazda rotary's, an odd combination to be sure lol. Before he passed in 2020 he had assembled 63 2 rotor & 6 3 rotor engine's, so it's likely if he didn't know about it, it wasn't worth knowing. I'm not nearly to his numbers, I've assembled 18 2 rotors and I'm hoping to build my first 3 rotor very soon. Great video by the way 🤙 What an awesome rare piece. Keep up the great work fellas ✌️

This is an amazing rescue of a tired old motor. Only so few built and this one has a whole new life. Nick you should be proud to keep a historic item still relevant. I'd be proud to have this beauty in any muscle Dodge ( or Plymouth). It's a torque master factory built. Imagine this coupled with an overdrive tranny. You could tear up some asphalt with it✨✨✨✨🌟

That would be kool in a early 30's dodge 5 window with just the hood..carbs sticking out the sides

This is the most excited I have ever seen you dynoing an engine Nick!

This has become my favorite episode ...just love that 413 and how it runs ...beautiful !!

At about 25:42 I noticed that there is a provision in the dyno's software for AFR-1 and AFR-2, so each carb AFR can be monitored separately. A cool feature. The people at SuperFlow dyno must have had this manifold in mind when they designed it. Now, as to numbers.. the ram made max torque @ 3400 rpm. (500 lbs / ft). The single 4-bbl manifold made 459 lbs @3400, vs 470 lbs @ 3900. So the rams made 41 lbs more torque than the 4-bbl at the same rpm. On the street, its torque that does the job. Actually, HP is just an expression of torque at a certain rpm. HP = Tq at any certain rpm (HP = torque x rpm, then divide by 5252.). Last week I had predicted the ram manifold would produce only a varianse of 5-6 pounds from 3800-5400, and I was wrong. So I stand corrected. Apologies to all. Never the less, it focused its max torque more in the usable range for a big, heavy car than the modern 4-bbl. Nick, I thought you had said one time that the supplied Carter carbs were 750 crm; if this is correct, I wonder if (2) Edelbrock / Carters @ 600 cfm would have been a better fit.? Thanks to Nick and thanks to his customer for giving us a glimpse of what it took to be the king of the hill back in the early and middle 1960s.

This is why you take your motor to Nick's Garage he cares and Know's his Stuff!! I would certainly get Him to rebuild an engine if i needed one done without a doubt 🙂

That 413 is awesome in every way Nick. It looks beautiful, sounds beautiful, and the torque and hp are fantastic. Awesome work Nick 👍👍

Hey Nick, thank you so much for posting this fantastic series of videos on this great and rare Chrysler muscle car and its incredible engine. I absolutely love vintage high performance engineering, especially from Chrysler Corp. This video proves the engineering concepts behind ram induction, and cracking the bellcrank pivot open and watching the instant throttle response and the awesome sounds this engine makes is indeed what it's all about! I also own a 63 Chrysler 300 J with the original solid lifter camshaft, and it runs (very) strong. The reliefs in the stock air cleaners go on the outside edges, they are for hood spring clearance when the engine moves when revved. Speaking of which, the stock engine mounts tend to break on these, and are hard to find and expensive. I drilled mine out and ran a 3/8" grade 8 bolt through each mount, and it does not cause a major increase in engine vibrations being transmitted into the body of the car, and then you do not have to worry about breaking the mounts. Also, i might suggest that you get a copy of the factory 300 J shop manual supplement, as it has all of the measurements, specifications and procedures for setting the complicated throttle and transmission kickdown linkage adjustments, etc. By the way, the factory 727 transmissions in these are basically the same one installed behind Max Wedge engines. I might also suggest that you have the power steering gearbox rebuilt while the engine is still out, as it is very difficult to remove with the engine in the car, because of the cast iron headers. There is also a rubber insulator that goes on the end of the steering shaft that you can buy on Ebay, and a small copper ground strap for the horn to work that goes over the insulator. Thanks again so much for these awesome videos!

VERY COOL!!! This engine rivals the HEMI in my book for mystique. Really cool to see what the difference actually was and prove the setup it works!

Wow! Great video. I love the sound of a big block V8. I've rebuilt several engines in the past, all Fords, although I've been around a lot of Mopars in the past. A few 383s and 440s. I could just imagine how Nick and Nico felt when this engine started for the first time. After a long time building it, there's nothing like the feeling of when it turns over and starts running on its own. It makes you feel so accomplished. Thank you for sharing this moment with us. I love the 60s Chryslers. I love everything about them, including the sound of the Chrysler starters. That sound brings back great memories. I know there's no place Nick would rather be, right t here with his 413. I would also add Nico is very lucky to be a part of this fantastic 413 engine. most of the kids today will know how much fun it is to have a big block V8 in their lives. Chrysler has had some major automotive engineering firsts. I'm so glad Chrysler is still with us. This is my first time watching one of Nick's videos. Nick I'm sure is happy to be sharing his knowledge with Nico. There's a great bond when you're able the teach someone what you know. This video got me pretty emotional, in a good way, I sure didn't expect that. Best of luck to both of you. Have fun!
