Edelbrock VRS-4150's on a TUNNELRAM INTAKE!! If one VRS is good.. Will Two be better on CASPER F100 

I can't believe the performance of these carbs! I think once I run mine a bit I leaned the screws a quarter turn. Response and power is amazing! I'm running the 650 CFM on my 68 Ford Thunderbird with 429 Thunderjet

The die-cast of your truck are awesome. Didn't know anyone could do that!

Besides the linkage side studs being longer, and having the nuts up higher. What if you used bolts to hold them down? Bolt head wouldn’t stick up like a nut and stud… maybe you could get the the mixture screws better then..? 🤔

Thanks for showing all the pros and cons of your combos. That for documenting all these different setups so we can be more informed about what we are getting into. Can't wait to see how it operates with the caspermatic transmission. I plan on using a pair of 500 CFM AVS2 Edelbrock carbs on my Edelbrock TR5 tunnel ram on my 318. I plan on trying progressive linkage and using the rear carb as the main. This places the primarys close to the center of the plenum. I want to install temp probes in each exhaust port and O2 sensors in both collectors. I should be able to dial it in quite well and see what is happening so as not to lean it out too much on a cylinder. If I have to I will run straight linkage but prefer progressive.

Hi Andy, just checking in for the algorithm and getting ready to watch these nice looking carbs do their thing on Mixed Up Boss!

I'd like to see a set of Holley NASCAR carbs ran for comparison...have two 390 CFM NASCAR Holley carbs from a top cup team on a tunnel ram'd stroked 347. The work that goes into them is unbelievable... all the machining down to hand blending on the rolled radiuses. The knife edging on the butterflies is cool to look at. I have the data sheets and the smaller NASCAR 390 carburetor flows close to 750 CFM

Looking forward to seeing how well these work, I plan to run them in the same configuration on a LS engine. Thank you for making content with tunnel rams and these carbs

Those carbs sound excellent, be curious if they make much difference, in horse power, thanks for sharing, all the best to you and your loved ones

That motor sounds great with that solid roller

I'm thinking that you should mount a vaccum Gauge. It would be interesting.

Them some nice mixers.

Nice! That is why I use Edelbrock carbs.

Casper sounded like it was very happy, didn't miss a beat. I'm impressed. I feel kinda lucky that I only need one!

❤ 100 percent awesome I am not a racer but I do love to Goof Off on some back roads I've never had much luck with Holley carburetors they've always seemed to be so finicky I always like to set it and forget it I get from the ASV series I really wanted to see one of these in action thank you Andy for making this video⛽️🇺🇸

Those carbs look awesome sitting on top of the Beast !

Those look very promising for the tunnel ram. Im going to hold off on buying carbs until you get these all tuned. But still they look to be very streetable and responsive right out of the box. Very Nice. Tunnel Ram Mafia

Good video! I like the carbs!

That smooth roll on to power and smile says it all! Sounds healthy for out of the box settings.

I can't wait for you to put your hands on them ( tune)

Edlebrock :) It’s not just a name

Happy Birthday! great vid, looking forward to dyno testing.

Casper sounds awesome brother! I think with a little tweaking you'll be able to get those just about perfect. Love that truck bro 👍

Im looking forward to more testing and comparisons to other carburetors and intakes. I would like to see more testing with a Holley high ram.

Looks like you are having a blast as always in Casper. Those carbs have Spivey magic in them!

Andy, those annular boosters make all the difference!

I would like to see the plugs just as you run it here. Vs the Doms that were on it.

I could tell an immediate power difference. I can not brag on those enough. As I told you when I spoke with you. Mine drove better than it’s ever drove and had a incredible response

Hi Andy I think 80 percent of the people that I see try to play pro stock when it comes to choosing a carburetor, my friends camaro had two 650 holley double pump with the choke plates on them with his tuning this car ran in the 7s at 170 mph in the quarter mile with a standard bore 454 , this should show people that you don't need oversized carburetors and also I can't believe how many cars I raced and beat back in the day with a holley 2 barrel that I used forever, thanks for sharing with us 👍

Since all the carbs you've tried are 750's, I don't see a lot of power difference between them. I have a pair of 750 holley track warriors on a t-ram BBC and i'm considering trying a pair of 1050 dominators. I expect to gain some power but possibly lose driveability but since its a race car thats not a big deal. Good on you for doing this testing and i'm glad those edelbrock carbs worked out good.

Cant wait to see it with the Caspermatic in it. Ive since went and watched all the videos from Cope on its development, and wow, very impressive!

Awesome carbs! Track tests will be fun 🤩

Thanks Andy! When it worked right I loved the stock Quadrajet that came with my 70' 429CJ!

So Cool!🔥 They Look Awesome On Your Engine too!

That is a good test right out of the box

Im sure that there’s gonna be some tuning involved. But I told you you’d be surprised by these carbs. Specially when it comes down to tuning them.

I think you are going to end up with a good drag and drive truck. Just add A/C. LOL

Can't say I'm surprised, I can honestly say I haven't been disappointed with any Edelbrock products, that includes 11yrs of commercial engine building, everything from stock reman. to NASCAR, with high-end street race/drag race in between. I thought the A/F ratio was a little on the fat side, as an out of box carb SHOULD be. Like Andy said, a big overlap cam makes hitting the A/F a little 'different'. The long overlap puts unburned fuel in the pipes, and the low man. vacuum will try to hang a standard power-valve open at idle. Basically shows how good the Edelbrocks are - the drivability is still good on a tunnel rammed big cammed engine, for as hard as it is to hit something good right out of the box.

You should try 2 shear plates under those carburetors I have it under My 1050 dominator it really picks The velocity and really help that Tunnel ram all across the board.

Throttle response seems better now, but it was good before. I think I asked about data logging once before. Would be cool to see how the A/F looks under load on the track. Will you leave the rear end gears as is with the Caspermatic? I imagine first gear ratio will change? And you're a better man than me... I would never take Casper on a slightly damp road!👍

That is impressive. WOW!!!

ATM may be releasing 4 circuit dominators

Annular boosters make such a big difference in terms of drive-ability. The efficient atomization translates to much better torque production down low. Aewsome video as usual Andy. Cheers. 🍻

They should be good carbs at $800.

The venturis are smaller of course it will respond better !!!

BLUE OVAL Nothing else matters.

What size carbs are they? You didn’t say. I have a warmed over 468 , Howard’s hyd roller cam 226/232 at 50 thou, 570/580 lift. Mildly ported Merlin oval port heads. I have an Edlebrock street tunnel ram. I’d love your opinion. Run the 650 VRS, but unfortunately they come with downleg boosters, or the 750s with the annular boosters??? Love your vids

Man, Casper seems to really like those VRS carbs. I'm thinking more and more I need need to get away from this Demon and get me one. Like you, I've lost count of the hours I've got in that dang thing and it's still not even close to right. Don't get me wrong, the Mighty Demon is a great carb, but I'm really beginning to wonder if it and my engine will ever play nice together on the street. 🏁

I love rolling burnouts. 😎

What are you setting the valve lash at? It’s kinda loud?. Respectfully sir.

Great vidja Andy awwooo🤙🏼 I gave Franklin dude a sub for ya brother

Absolutely love your videos!

I might have missed it, What jet sizes do them come with?

It's Amazing how a 700 hp truck is such a gental giant awesome carbs

Hey Andy my buddy is putting a 8-71 supercharger on a SBC and I have heard that the crank should have a big block snout on it or it will snap the crank off right behind the timing chain. now some say if you leave it low boost it will no hurt it and if you use more boost the crank snout will break. I have seen crank snouts snap off and want to know if you have any info about it.

Very interesting! Great video as usual

Andy, I was wavering but how could one?!. Will buy the same Ram as you have and the two carbs. Carbies, any day!!! Cheers, Adam.

What tunnel ram should I run on my 454 oval port. 10 to 1. Comp xtreme 286 grind. 238/246 exuast duration.

You're probably atomizing your fuel a lot better with them small boosters at lower RPMs you will not make the power on the high side like you will with the dominators😊

Sounds good looks good runs good great job wouldn t mind a hotwheels of the truck

Was there any good reason for the mounting stud to be directly in front of A/F screw ... like, main body design was good for 100 horse so it had to be... If not thats freakn REDICULOUS..!!!! That would greatly affect my decision in a purchase. Thanks for the vid..? how is it going with the new seat install.?

Just got my 1407 tuned to my stock 1980 c30 454.

Great video Andy!

Great info sounds good

Remember your baseline your timing your idol your vacuum you're forecorner screws changing else you can think of to go back to.

Are you gonna have rematch race with Tony an bootlerocket ?

Now put a 1 to 1 linkage set up for better fuel distribution?

Hello Andy, yours and Mr. Visards videos are always so informative please keep up the great work. Off the subject for the moment, I own a few small block Chryslers some of which are magnums 5.2 & 5.9 . What is the constant for the " 128 formula" for small block Chryslers in the 8.5- 9.2 compression range? I am looking to get as much daily driver torque & mileage as possible. Any and all help is greatly appreciated. PS: one is a 2001 Dodge Ram 1500 4x4 w/auto tra😅ns 318 & 3.55 gears. Another is a 1990 150 2wd auto unknown rear gear. Both are fuel injected. Thanks again, James Browne Stedman North Carolina 28391

More improvements to my favorite truck !

Hey andy i be hearing alot of speed of air pistons. Could be good Content for you and david to test on his Mustang.

Are quick fuel carbs any good I purchased a circle trac carb from holly for a 350 chevy 750 double pumper I see there not available any more ,P/S have not nun the car yet still under development If you would let me know Thanks

Drives nice. Can we get back to the track and try to get somewhat close to showing 700 HP?

Just ordered my progression ignition HEI distributor for my big block Chevy. Should be here Wednesday. Anything special I need to know?

Does the engine needs to be under a load to measure afr? Or is free reving without a load sufficient?

And y can you please show us how to tune one of these the way you do it.

Quadrajets!, try those. They work the best period!

Great video as always!

Cool!

Has anybody boost referenced these carbs yet? For a roots blower application?

😢great you got them on

What does vrs stand for?

Glad to see that you are ok. I got worried about you when DV said something about a medical emergency. But I didn't know who. But it's none of my business.

I want 2 950's

These Edelbrock carbs look an awful lot like Holley now .

So streetable wonder if your has mileage goes up

Edelbr🥝+🥝ck VRS = ✔️

Focus on problems, instead of "issues".

sweet

It will be a least twice as good

Typical fat "out of the box" calibration to try to cover most engine combinations. Fat always makes the engine seem more responsive and smoother. The challenge is to get them to run lean and clean and still be responsive. A good 2 circuit dommy will do that too. And yes, for an engine like that two carbs should always perform better than one due to less pumping loss and better intake runner distribution

Thank you for your knowledge and videos USA 🇺🇸 TRUMP 2024

Mixture screw gripe? I'd call it yet again a manufacturer using full paying customers as beta testers. What an utterly ridiculous oversight. How could this ever have been allowed to make to full production? We hot rodders aren't financial units to exploit - sorry my bad, yes we are.

🙏👌👍👍👍👍👍👍👍💪

Great video as always truck sounds and runs awesome Ford power forever baby a real Chevy and dodge killer l love it keep on bringing it
