[@deesel666ify]

This is excellent information. I just switched my 468" big block Chevy from a 850 double pumper and air gap to a tunnel ram with dual 750 double pumpers. Took awhile to tune, but now it has every but as good drivability as the single carb and get the same gas mileage, but has considerably more power from 1800 rpm all the way to the top. The torque gain was nothing less than impressive (actually shocking). It's hard to get good information on dual fours and tunnel rams on the internet- everybody says can't use a tunnel ram on the street and the only work for high rpm racing engines, which is exactly the opposite of my experience. This video confirms everything I have learned thru the experience of using a dual four tunnel ram. Tunnel rams kickass.

[@robertmoon906]

I had a Holley 4 barrel 850cfm double pumper on my 351C engine in my 1972 Mercury Montego. Went to Weiland Tunnel- Ram and 2 Holley 450cfm carbs on my 351C. The carbs worked perfect out of the box. Minor air-fuel adjustment. Looked better in that big engine compartment. One turn of the key, starts like Fuel-Injection. Nice.

[@steveadams5190]

I'd love to hear what Andy would have to say about dual quads on top of a blower. I realise that that's a whole nother animal.

[@stuartbuckley8720]

It's pretty much straight forward just like the tunnel ram. The carbs are a metered air / fuel device and tuning follows basic rules. The main difference is in carburetor size so you don't restrict the blowers ability to pull / push air into the engine

[@albertgaspar627]

run a centrifugal blower rather than a roots design--that way the boost goes into the carb, enjoys the cooling benefits of the venturi effect, and you don't get the lag inherent in a front mount intercooler. you are limited to the amount of boost where this works, but boost really just measures how much "resistance" the head port is giving anyway--invest in a good head design, less boost is needed to make the same power.

[@livewire2759]

Excellent video, excellent information. I've been arguing for years that you can get great economy with a performance engine, simply because the same principles apply. Every single engine modification to make more power, does so because they make the engine operate more efficiently. The more air you flow, the more fuel you CAN flow, but you don't HAVE TO! If you don't get good mileage out of your hot rod, you simply haven't tuned it right, or you can't keep your foot out of it!

I’ve got a friend with a rat rod and the tunnel ram like 12:00 . He has progressive linkage and refuses to change it and I runs like crap. I put a bolt in the slotted linkage to lock it and after a little tuning it runs like a beast .

[@williamcarey6592]

Great, I am building a 2-4 setup on my 355Chev engine using a Edelbrock manifold and AFB Edelbrock carbs. This is to be a retro setup modeled after a setup I ran at least 50 years ago in the same car. Yea it’s a 39 Ford I have had for 55 years running Cheep Chevrolet motors that fit easily in the engine compartment. I say cheep because the most I ever paid for a rebuildable core was $10. The 350 is a 73 4 bolt main forged crank one that was free.

[@SweatyFatGuy]

Agree on running engines you get for dirt cheap to free. I've never paid more than $150 for a Pontiac 400 or 455, usually get them free, so easy to make 500hp/550ftlbs with them, cam, lifters, headers and you're there with a 455 running any year of 400 head. Some of the 400 heads require race gas or E85 because they make 11.3:1 or more compression on a 455. With how cheap E85 is, thats what I do, just crank the compression up with small chamber heads and enjoy the torque. The pump gas 455s I built for less than $2000, bored .030 over, balanced, good machine work, but nothing they don't need like honing the mains, make enough grunt with 8.8:1 compression to push a 4100lb 70 GTO into the mid to high 12s with a 2.93 gear behind them. Yep, not a typo, two ninety three. And a stock type converter that stalls around 1900-2100. One of them was built in 1995 and its still good, no ring ridge, no blow by, and it was my daily driver for ten years along with getting raced often. Getting a cheap or free engine and rebuilding it like Tony does is fun, I simply like to do it with more cubes. Tried it with a $500 sbc 400 short block, put vortec heads on it, and man that thing nickel and dimed me to death, sure the heads are $300 a piece, but then you need all the special stuff that fits them, and suddenly you are over $2500. Compared to my Pontiac 400s its a pooch too, because the valve guides won't let you run more than .465" lift, so that is more machine work and money. If it would stop leaking from a different spot every time I run it, I might be more inclined to like it. Less torque for the same cam timing than my Pontiac 400s, less power everywhere, and the leaks..no wonder RTV is so popular. The LS costs a lot more, but they don't leak. HotRod magazine lied to me saying the vortec heads are cheap power.. would have been less expensive to put some AFRs or Edelbrock heads on it. It might be cracked, the sbc likes to crack things. For a basic driver you pull out and stuff in the chevy works pretty good. Very easy to find parts, usually not overly expensive because you can find stuff used easy. I had to buy new with the 400 because nobody had parts for it around here. Making the power I get from my Pontiacs with one costs more than I want to bother with. These LS swaps are pricey, doing one on my 76 C10, even using parts from engines I got free its expensive. I like them in my 98 Formula and the 4x4s I run in the winter, so I figure why not the summer truck too? I hope the 6.0 makes decent power, the one in the 99 Silverado 2500 runs pretty good for such a heavy truck. The 76 came to me with a 305 that developed a death rattle, I put a 400 Pontiac in it for about 8 years, then needed that 400 for a GTO build, and put an 86 454 in the truck, man that thing was a gutless pig that drank gas, seriously 4mpg in a 2wd short box half ton. Changing the cam, intake, and probably heads on the rat was going to cost a fortune, so I went LS in it. People have been giving me 5.3s for free lately, with the entire truck. As long as you use all used stock parts they are pretty cheap. Making them run in an older vehicle is going to cost more though, its $700 just to make it run after putting it in, doesn't matter if you run EFI or carb. Fun stuff to play with though.

@@williamcarey6592 my first ex was a used 1974 model, the second ex was a spanking new unused never driven 1982 model. I am from 1969, one of the good years, so I am appreciating in value, but the suspension is worn out and needs rebuilt. When it comes to cams, bearings, etc, yeah I get all of that new, I see them as consumables. I have a virgin 400 block on a stand, so I am thinking it needs a UT rebuild, rings and bearings with a bit of a hone. Throw some of my 72cc heads on it, a RA IV cam, used springs, new oil pump, stock intake, E85 Qjet, and stuff it in something light. Sounds like a $350 engine that in a 3000lb car should come real close to running 11s with a 3.42 gear. I want to go 11s in this 72 Ventura for less than $1000... excluding wheels and tires, because hell those alone are a grand. The car itself was free, and its been sitting around for over 20 years now. Its a reason to make videos. Figure I will do that while I am waiting for the aftermarket block and 4.5" crank kit to show up so I can dump it in something like the 68 LeMans or 65 LeMans gasser with the heads and cam from my street strip toy. Probably the 68 because I can fit a lot more tire under that thing than the 65. Should be over 800ftlbs from 3500 to 5500 with that setup, all motor. Fun times. The reason for that one is to go embarrass people who say Pontiacs will can't run faster than 13s.. lol

[@johnfestich5008]

Great video. Props to Uncle Tony and Unity Motorsports! I wonder how mild street engine.. say, a 383 stroker or any of the other American v8's would perform with 2 GM 670 cfm TBI units on top of a dual quad manifold. It seems like atomization would be better right off the jump and tuning would be done with a laptop and wideband O2 sensors. I think it would actually be simpler to tune, better drivability and economy and would automatically adjust for ambient temperature and altitude.

[@Fubarfighter]

Really great video. I am sure there are more nuances than this, but very educational. As UT said, they put dual quads on bone stock engines for 65 years and they worked well on the street. But you can't go all Glidden and Allen on your stock 289.

The reason for the change was low speed drivability, I'm definitely learning something watching this.

[@ks_1111]

Somewhat related, as i'm looking into a tunnel ram.....I got a 400 sbc on propane that i'm looking to hop up. In my research looking into tunnel rams and dual quads. I learned that the tow truck guys with the 350 chevys and and 351's in the fords, and the chevy/ford big block guys. Actually preferred tunnel rams and dual carbs for their propane powered trucks. They got better low end power out of the trucks over any regular hi rise or stock style intake with a single carb. And they even got better mileage, one guy supposed picked 4mpg in his 460 big block ford tow truck

Can you run dual TBI on a tunnel ram?

[@UnityMotorSportsGarage]

yes you can... Years ago.. I did a Holley Projection setup (Ancient first aftermarket TBI injection back in the 90's) for a guy on a tunnel ram and it worked amazing!

[@jamesford2942]

I have set up dual quads on a few hot rods. Two had tunnel ram and one was cross ram. The tunnel rams were set up with progressive linkage. The thought is that the rear carb is the primary and the front is the secondary. The primaries of the rear carbs are located near the middle of the plenum and feed all cylinders fairly well at low throttle and RPM. As you open the throttle and tip onto the secondaries of the rear carb the primaries of the front carb begin to open as well. This is like having tri-power carb set up. Fuel is evenly spread across the manifold plenum. At WOT all 8 barrels are open and directly over the intake runners. This is like having stack injection but with the plenum to absorb the reversion pulses. When you use the tunnel ram with a single 4 barrel you will have the same bias on the cylinders as the dual quads with progressive linkage except that it is the opposite end of the intake. One thing I will say is that you have to have an open plenum rather than having a center pinch between the two halves front to rear. With the cross ram it it has the two banks separated so you have to run the carbs synced and should use smaller carbs. It worked ok but had a tendency to over fuel the engine.

2-450 cfm vaccine secondary carbs. Please could you provide that info?

Hello Tony. I have a few questions about transmissions. I wanted to attach them to a transmission video. I looked through your video list twice and to my surprise, you don't have one. Yes, transmissions are a child of another god we don't talk to much. I would love to hear your opinion of them. The good, the bad, and the ugly. Also, I heard of a guy once. He put a 1500 stall torque converter in a 350 Camaro. Legend has it he got 35 mpg out of it. If/when I get a Camaro I would want to drive it. Not just in circles. How would that work? Is it viable? Is it stupid? I would love to hear your opinion.

Where can I get the linkage for a dual quad 318 poly engine, I’m building a home rebuild, thanks

always wanted to try 2 Q jets on a tunnel ram...

Ok, I’m one of the less mechanical guys but I do love the cars and the looks of the duel quads. I have a 66 Impala 327 4 sp car with a 308 gear. It’s the 275 ho version. The car runs great and is very cool but I wish to up the coolness of the ride. I just picked up a GM dual quad intake from a 61 Vette, Uncle old car parts. I would like to run it on my 66. Can you advise if the Holley 390 CFMs would be a good fit? How about the linkage. Im thinking you are saying one to one but not sure. I will likely change the gear to a 373 and add a small hydraulic cam but maybe not. Will it work completely stock?

Can I some how run one of these set ups on a 2002 5.9 magnum I can’t find any that are suitable for it or are intakes universal

[@marks8052]

so a six pack on a SL6 with the right cam,( maybe webers)?

I'd like to see and hear someone with a dual tunnel ram but with 2 tuned thermoquads 😁

750 brawlers on my 383 and she runs 10.7 at 130 mph. Little confused on progressive not being ideal for tunnel rams. Mine runs superb on street and strip 🤷
