How to Build a Tri-Power / 6 Pack / 3 Deuce Carburetor Setup - Stacey David's Gearz S2 E5

[@knightmare1015]

An oldie but goodie. The old 6 pack did great in town or for some simple light cruising and you didn't burn a ton of gas either because it keep you running off the center 2 barrel carb. That changed once you stomped on the throttle though. You could literally watch that fuel guage needle drop like a lead brick. Hard to believe that when I was a kid, we use to hear people bragging about 12 and 13 mpgs.

Back in the day I had a 1972 Vega GT hatchback, yeah I know a Vega? Well Motion Performance, was building V8 Vegas and had a V8 swap kit that wasn't all that expensive. You needed to find a rear to fit, which also wasn't that hard. Small block Chevy's, 283, 327 and 350 where everywhere and cheap too. Edelbrock had a 3 2bbl & 2 4bbl manifold for the small block. Wanted to do it, but never did. There was nothing like a Vega rolling by with the rumble of a small block.

Stacey David you rock man

Thank you!

[@volkerjanssen7905]

G'day from Oz, Stacey. I only just found out about your channel today. Really helpful for the GM-V8 novice. 👌👍

[@OfficialStaceyDavid]

Glad it was helpful!

I've never owned or worked on a VW, but my aunt had one when I was a kid, it was a beautiful blue 1974 Beetle

[@THROTTLEPOWER]

Very cool, have always liked that set up!! 👍👍

[@johnglielmi6428]

I love the shaker hoods on muscle cars!

[@offroad4x4nhlife45]

I wouldn't mind a dual quad setup on my Cleveland

[@timr31908]

The most famous was Ford's 401 1961... It came out to beat Pontiac and it did.

[@timr31908]

I always thought two four barrels was a better deal and easier to sink..,.😊

[@twopistonpsycles942]

What size jets did you use in the tri-power 94s? Also, would you run that same progressive setup on top of a blown GM 350?

[@Vincent-ke5zn]

Way to go Frank, 2 cool 😎 VW cars 🚗

Mr Stacy I really enjoy the video about the tri power carb setup I have a question. I have a Ford mustang 200 I was planning on putting a Offenhauser 5205 on which takes 3 single barrel carbs is there a kits to rebuild a single barrel carb to eliminate the choke and the fuel air screws like in the video you showed, with the 3 duces. I was told it a good setup but tuning the carbs are a pain, the way you had talked there is minimal if any tuning to the outside carbs. Thanks for the help.

So just some clarification on the 500 end carbs ... I also have a 340 Six-Pack set up .. looking for some spare ends 500 carbs original parts numbers are 0-4790 rear and 0-4789 front .. i found both but between the price to buy and restore is crazy.. so I purchased a new center from Holley 0-4792 350 CFM .. I see they no longer remanufacture the end 500 carbs for the 340.. so I have been looking at the 500 CFM carbs for the 440 engine 69/70 Holley 0-4365 and the 1971 440 engine 0-4672 .. I've been told the 69/70 has a different style metering plate and the 71 has the same style metering plate that my 340 end carbs have in them, just a different jet size. Question: will either of the 440 end carbs work on my modified 340 ? and if so should I go with the 69/70 or the 71 carbs? Any help would be greatly appreciated from anyone who has dealt with this scenario. Thanks

[@Vincent-ke5zn]

I know that I'm changing the subject here, but what are you going to do with the 345 cu inch engine that you took out of the International tow truck

[@volkerjanssen7905]

2:20 Can I just use any Rochester 2G/2GC as the main? Shouldn't there be a specific jet size be required to plonk it on the Edelbrock with its two slaves? From what I know they come in sizes between 0.044 and 0.073 - which to me seems significant enough to make a difference...

👍👍

[@clevelandmaker386]

Where in the hell..... you can't find any two barrels anymore!!!! Private junkyards

[@Vincent-ke5zn]

You have probably rebuilt carbs so many times that you could do it blindfolded

[@hkrueger9235]

Hey Stacey David, maybe a dumb question but will any 2 barrel Rochester carbs work or is it a specific type/year that I need to look for? I found a guy that has several 2 barrel Rochester's of various years that I can purchase from but I don't want to waste money if it has to be a specific year/type carb. Thanks for the video and the input. Anticipating trying this tri-power out on my sbc 350!

[@OfficialStaceyDavid]

The primary carb isn't as particular, but the secondaries are usually specific. You can buy them already set up to be used as secondaries from some companies.

[@Vincent-ke5zn]

How about dual Quads (2 4 barrel carburetors)

[@joelmiller7]

Well actually 2v carbs are cfm rated different than 4v carbs … 1350 cfm 2v = 955 cfm 4v … still tons of air and fuel ⛽️ still way cool looking … lots of hot rods also run block off plates for the extra carbs (e.g 8 x 94’s is 2 x 94’s) … all the looks and just enough carb for a stock motor … cfm needed = (cubic inches x max rpm) / 3456 and the conversion from 2v to 4v is cfm x 0.7071 …

[@Vincent-ke5zn]

When you open the throttle with tri-power carburetors you better have a full tank of fuel also

[@gizzmo5952]

Can you get the manifold in a small block dodge?? I'm doing a 340 magnum for a 73 road runner.

[@OfficialStaceyDavid]

There were some factory 6-pack manifolds for the Mopar small block in the Challenger T/A and AAR 'Cuda, but they're expensive and hard to find. I'm not sure if anyone makes them in the aftermarket.

[@gizzmo5952]

@@OfficialStaceyDavid thanks Stacey. I found a complete stock set up for 1200 bucks. Going to put it on a AAR 340, and stick it in a 73 barn find road runner. Taking the stock 318 out. I don't know why they put those 318 puss buckets in a road runner, but I'm fixing that problem, lol.
