Why use the factory 4 barrel intake? It's gotta be 25 or 30 pounds heavier than an aluminum aftermarket intake manifold. They do make good rowboat anchors though.
Because: A) Not all of our viewers want an aftermarket manifold B) Not all of our viewers can afford an aftermarket intake manifold C) Some of our viewers work with engines that don't have aftermarket manifolds available for them. D) Some viewers are only wanting to maximize their otherwise stock engines E) Some viewers are mostly interested in restoration type builds F) Some factory cast intake manifolds are excellent pieces that just need refinement G) Because making improvements to factory parts can be very satisfying for some H) The sleeper effect I) Not everyone has a rowboat to use their old manifold on....
@@UncleTonysGarage You brought up something that has continually sat in the back of my mind. If smooth intake ports are better than bumpy, then why didn't they come from the factory smooth? I have forever thought if a car company can get better efficiency out of their engines they would do it from the factory. This video cements my theory of "not" making intake ports smooth. Voodoo sciences. Thanks for this one! and next question would be, what happens inside the head, bumpy versus smoothed? cheers
@@rockroll3983 Next time you fly try to get a seat by the wing. Hope for flying through rain. You will see the water droplets on the surface of the wing barely move, even though the plane is flying 300-400 mph. A droplet might take 5 minutes to go from leading edge to trailing edge. That's due to the boundary layer. The boundary layer lubricates the airflow of the layer above it, and that lubricates the layer above that, and so on. You want that effect inside your manifold, too.
@@UncleTonysGarage J) because Uncle Tony said so! K) because it's free and you know it fits and works with all your other parts L)...... I got nothing for L, but at least now you know a good portion of the alphabet! good luck with the rest (L)o(L)
I hope you have been watching Charlie's videos on your 318. He is doing an incredible amount of work on the heads and the single and dual plane intakes with all of the numbers you can ask for.
SmarterEveryDay has some interesting stuff. A while back they had a transparent carburator showing the venturi effect in the carb. He recently had a video showing fuel injectors being tested and how they inject fuel. As a bonus he had a real neat video of an electric engineer who worked on the Apollo mission giving a tour at the rocket center in Huntsville where they made the Saturn V rockets for the Apollo program.
Been watching Garage54 for years. Those guys are great. They do some of the most interesting stuff, and then follow it up with something hilarious. Like making a Lada that does a wheelie, (with some help) to making one with square wheels, or the screw on the driveshaft to try and assist a Lada go off road.
Gearheads are universal, no matter what language. I watched the differential and oil pan episodes and I must say that it knocked a couple of things off of my gearhead bucket list. I still want to see one of Ernie Elliotts intakes from the late 80’s to early 90’s cut open and dissected. We were told Swirl technology, but I would like to actually see one.
Of course , back in the day believe it or not hot rodding existed in europe too with just another name. I remember gearheads butchering 2CVs into speed machines with no money
I'm pretty sure Smokey Yunick made an intake that made the mixture visible while the engine was running. He described in his book that at wide open throttle there would be streams of fuel running along the bottom of the runners. The Garage 54 guys had a similar experience, IMHO. Pretty cool to finally see it. Thank you for recommending it!
Loda Ladas. :-). When I went to Ukraine in 2009, many taxis were Ladas. Some Volgas ad a few Chev Aveo, built in Poland. Virtually all were manual transmission. One Aveo had an automatic. Virtually all the carbureted cars popped through the carb. Accelerator pump probably set for minimal pump shot to save on fuel. All the injected cars had the check engine light illuminated, probably for a similar reason. They fiddled with something for fuel economy. Those guys at Garage54 are pretty inventive guys. Have to give them credit. Now the one where they cut one Lada engine in half and welded two cylinders on to another engine and did the same to the crankshaft was definately out there to made a six. They did get it running.
Tony you're killing these days. Really good shows lately. Hope some day to cross paths and shake hands or bump knuckles or what ever. The guests on the show cool guys. Always looking forward to next show.
I just got those Chinese afr enforcer heads the dna version and a eldebrock air gap Nascar (its black and cost 200 more) on ebay for the price of a speed pro going to do a 1206 to bolth but ended up with a 4340 forged stroker crank and h beam rods so should have whent a single pain and whent all out
Garage54 guys have a great sense of humor. Square wheels, see through oil filters, sticking BBs in the cylinder. There is nothing so ridiculous that they simply will not do it. I love em for it.

Uncle! Thats why I never liked that mini manidold you use in dartbdaily driver... I must agree wirh you on those guys, really good and creative content
Interesting about how you want the runners bigger than you think they should be. Stock 74 318 I'm my 3/4 pickup. Had a 68 340 intake slapped it on with a 625 Carter AFB. Yep there's that mismatch but it worked well and after some jets and rods got better mileage, made more power than the two barrel. So I score a cheap SP2P and think more mileage and low end torque! Actually the mileage and power everywhere dropped. Tried jets and rods but never got the mileage back to what the old 340 intake did. Next step is a 273 I just picked up, the SP2P will be used for a door stop or scrapped. 😂
I've had the same experience with the SP2P and the one I have on my wife's daily driver is coming off to be replaced with a stock 340 piece. It's one of those things that works well on paper, but not in actual use.
If ya wanna see something look at the old torker 340 manifold, notice the sharp turn the airflow has to take on the outboard ports , right where the manifold runners and head ports meet ,the airflow basically slams into the side of the port
Hey, maybe you could mill the top off the runner of a intake , and glue a strip of Plexi on the top, , maybe put a led inside, shining into the intake runner of the head, so it can be well seen, or use a piece of glass, so it can be seen better, that would make a cool video, if you have a garbage intake!
I'll throw the firebird's .02 I ain't scared! I love the Lada torture videos! He executes grand, bold concepts and the Ladas are the only looses. Firebird out
F.I.A.T. built a factory in the former Soviet Union and they started building F.I.A.T. 124 sedans, under license there. The Soviets named the product "LADA" and reportedly built them with thicker sheet metal, in order to better withstand harsh salty winters. They dropped in their own designed engines of which were single overhead-camshaft types. The Italian 124s were using smooth-as-silk dual overhead-camshaft engines
I suppose that it's like the dimples on a golf ball help it to travel further because of reduced drag, so the roughness inside the runners reduces drag on the air/fuel mixture. I remember back in the mid to late 60s, porting and polishing was a common thing. I guess maybe the polishing wasn't such a good thing after all. Didn't Richard Petty run a vinal roof on #43 once and felt it was a bit faster? Or did I dream that. Oh well, cheers 🍺
There is a video on RU-vid, where there's a discussion between an interviewer and Ford guru John Kaase. In it, as a part of the discussion about intake manifolds and their internal characteristics, Kaase says they drilled a hold in an intake runner, then capped it with a removable plug. After they got the engine running on a dyno, they slowed the engine down and Kaase stuck one of his fingers in the hole. He said he could plainly feel reversion, sort of a standoff. He could feel the air moving down the intake runner, then could feel the air moving back up the runner. Also, the air in the runner was very cold due to the effect of the atomized gasoline on the air in the manifold. I thought it was very interesting that there was reversion / pulsing back and from the air hitting the intake valve and then bouncing back up the runner in a "normal" dual plane intake.
Sonic pulse, waves moving back and forth... there is a section in the now out of print (but you can pick up used) "The Two-Stroke Tuner's Handbook", by Gordon Jennings, where he discusses how tuned pipes work. You can find this online downloadable as a pdf at no cost.
I could very well be wrong, but UT's description off how atomized fuel and droplets are behaving inside the combustion chamber might be more theoretical in nature rather than factual. Love his insights anyhow.
I generally don't gasket match. I line match. I usually take the gasket and use a sharpie to line around the inside of the gasket port shape. Then grind to that. I do both heads and intake. you end up with a smooth transition, but not a velocity change from skinny to wide and back again.
i was just wondering if you knew about garage 54 when i saw this video. i wasn't sure what your take on Russians was after i hear what you think of China but I see you're cool with gearheads from other places.
Did this back in the mid 70s good to see physics has not changed and if you want to increase turbulence in the manifold shot blasting works a treat but need to experiment with shot size . On a 3.3l straight six , Perspex manifold lost 6hp the biggest gain on shot blasted was 10hp on a chassis dyno. From memory it was a 200hp motor good power for the time . On a race engine every little bit helps
The Lada is actually an entry level luxury car. Models go between 60 to 75HP and feature all basic car functionality with some fake leather and wood interior pieces and a 2 barrel carb. Moskvich (de-tuned bmw engine) is a budget car, as it lacks some basic functionality, has a manual engine crank when your battery inevitably dies as you can't afford to drive it more than once a month and has no more than 50 hp and could barely go up a slight incline. The trabant (manufactured in west germany) is the true actual budget entry level car. It is FWD transverse air cooled 2 stroke engine, has fiberglass body, shares a single leaf spring between both rear tires, has all around drum brakes and dashboard has only a speedo. At least it has a starter as big as the ones used on Ladas (the same as the 3 cyl wartburg 353) and 4 speed transmission with a one way clutch on 4th gear (to prevent oil starvation in engine braking conditions)
A good channel to watch is Junkyard Digs he explains how everything works. Also Thunderhead289 he made a lawn mower carb to work on a Ford V8 got 40 mpg
Uncle Tony, could you answer this question for me and maybe anyone else who is curious? I had my heads milled ten thousands I believe to remove a flaw and was wondering do I need to have the intake milled to Match this before I could even try gasket matching my heads to my intake? Thanks in advance if you happen to see this. RM
Once upon a time. Somebody was making intake gaskets with fine screen over the ports. Allegedly to atomize the fuel better, car needed/wanted way more jet in order to run normal.
I have a set of those for a 4.7 magnum. But these were designed for idiots putting the old plastic manifolds on after a catastrophic failure and destroying the new reman engines. Never heard of any other reason for it
Some pretty interesting stuff. I just cleaned up the old spread bore intake that came on my 327 large journal today. I believe it’s original, 1968. I think I’m going to finish cleaning it up and run it for a bit on the 327 and start with that. I’ll probably run it in the 55 Chevy for a bit just to see how it goes. Honestly I’m sick and tired of all the bolt on crap and I plan on building a 68 Camaro for the wife in the future and this would make perfect sense to keep that way. Good stuff.
You brought back memories of the engines I ported, back in the 70s. Never polished the ports, not logical for street engines. Seasoning the intake, always important. I'd watch your Live Streams but the sound always fades in and out and has an echo, like in a bathroom.
If anyone ever wants to do a clear item, like the one mentioned let me know. The company I work for is a plastic shop. We specialize in all things plastic. Northern Acrylics based in Duluth Minnesota.
Great video Tony. Previously when you were talking about the Slant, you said it’s the worst inline 6 when compared to the Ford and the GM. Can you explain why you said that please. I’m trying to see what makes some inlines better than others. In the world of straight 6’s, there are so so many. Triumph looks identical in bad design, then there are the Datsuns, Nissans, Toyotas, etc. I’m rebuilding a TR6 and using much of your information, as well as David Vizards passed on knowledge to make it the best I can. Thanks again Tony, all the way from Ontario.
Uncle Tony, I seem to recall you talking about issues with gearing on the tour and I have a serious question. What's your take on the Gear Vendors "overdrive" unit? I understand the theory, but I'm unfamiliar with the unit. Please let me know because I'm thinking of buying a used one but I'd like it if you weighed in first. Thanx!
Tony, While on the subject of intakes. I have a later model Jeep 4.0 intake. The curved horseshoe not the squared off one like yours. It is supposed to flow better then the earlier model. I would be happy to donate it to your build. Just let me know where to ship and its yours...🤓
That was an SP2P intake on a 318 head...but yes, I did blend the transition. It was also a disappointment in the bigger picture, and the plan is to redo the top end of that engine sometime this year
I love garage54 and there crazy Russian shenanigans the voiceover cracks me up! project farm is another good channel when it comes to see through parts!
You could buy high performane parts right from Lada. Quad intakes with 4 one barrel carbs, cams, headers....for rallying. I knew a girl who's dad was the Canadian importer for Lada.
Ports are always mismatched on purpose. The hole in the manifold is always smaller than the port in the head. It's to reduce reversion and boost low down torque. If it's an aftermarket part then anything is possible and you definitely don't want the manifold runners bigger than the ports in the head.
@@peaceonearth8693 sharp corners make fuel drop out of the airflow. Like how a centrifugal oil filter works. Darned fuel molecule couldn't make the corner and ended up off in the rhubarb! 😃
So is it like gas condenses on cold surfaces is that it, like water might? I would like to see what would happen if they put a heat gun to one plastic runner only and see if anything changes.
What would your opinion be on putting together a SBC with 1 .030 over piston, and the other 7 being standard bore size? Assuming they all weigh the same. Also, all the other bottom end parts would be new as well as the pistons. Would this be acceptable for a street/strip engine? Thanks.
Just for reference I bought a bike that was raced in a spec (supersport) series that had the 2 inside cylinders overbored for more displacement. It revved to 11 grand all day.
What about using 340/360 intake manifolds on 318 engines with 318 heads? There is a gross mismatch between the intake manifold ports and the head ports, but it seems to work. Would an intake manifold with 318 sized ports work better?
I remember reading something many years ago about someone that had a setup that pumped a sand and water slurry thru intake ports and passages to polish them. Anybody else recall that?
I am currently using iron performance heads on my sbc street-strip build which have larger intake port entries compared to the iron quadrajet intake manifold ports where those smaller rectangles of my intake meet the cylinder head such that it is not slicing the column of atomized fuel and air due to an interruption, but rather being led into a "larger room" so to speak due to the small-to-large transfer. do you think this would affect things other than just limiting my max flow based on the bottleneck of the intake?
Uncle Tony! Question! How do I know if my piston rings have the moly coating? I picked up a set today for my b18b1 and it’s Mahle brand. No info on the box. Got them from oreileys
