Default 283 Dual Quad Carbs question.

This is again a bit off topic but does have Corvette content. I've got a '32 Ford 5 window that is very close to being done.



It was an old rebuild (early 80's) I bought locally and then put this under it because the Mustang II front suspension and Pontiac V6 seemed sacrilegious in a Deuce coupe.



The rebuilt 283 (w/ 327 350hp cam) has an Edelbrock Tri-power and three 2Gc's that need to be rebuilt and configured to run as a tri-power. I've got Jim Lockwoood rebuilding a '58 fuel injection unit that will eventually end up on the car, but in the mean time I'd like to get the car running. I've got a dual quad intake that I'd like to run on it in the short term.



Would someone be able to recommend a couple of carbs I could buy to get this running? Obviously no need for "number correct" carbs.

The other issue I have is running the chromed Corvette generator.... it conflicts with the hood side. Any suggestions?

Thanks in advance. Hopefully there's enough Corvette content to keep this thread here.... I really could use some advice.

Thanks in advance.

Hopefully, Frankie will chime in here. Correct carbs are spendy. I understand WCFB's from period Buicks can be made to work. Be advised that these carbs are only about 380cfm....no real gain if any over the 3x2 set-up you show, other than your personal preference.

Thanks for the reply. I don't need correct carbs, just two that will work. The other option would to buy 3 2 barrels ready to go. I've done a little searching and it seems that's a little spendy.

That's going to be so sweet when you are done with it, Allan.

Is it an option to use an alternator in lieu of the generator? If so, it looks like there is plenty of room for one of the ultra-mini alternators down low on the driver's side of the engine. Several companies make brackets for low mount alternators or you could just buy a PS bracket and do some creative shimming to make the pulleys align.

Jim,

Good suggestion, it's just with the era of build that I'm after, the generator is far more fitting. An alternator just wouldn't belong.



Maybe I should just run the car without hood sides and the shiny generator hanging off the side........ especially once your beautifully rebuilt FI unit is on it.

I think I'll be running the tri-power with some rebuilt carbs until I can get the fuel injection on the engine.

Wow! Had no clue........ or is that the same guy with the $600 wing nuts?

LOL Too funny. Yea even clones it is crazy isn't it? Yup I would stay with the tri power until the FI is good to go.

I don't know any good reason you can't use any old WCFB's as long as the throttle linkage works.

I sold my clones to a forum member last year for $1,800 so that eBay price is not far out of line....he put them on turned the key and has been driving the snot out of them on marathon trips in his C1 and hasn't had to touch them. Here is what is crazy - I bought them three years before from Chicago Corvettes - yeah THOSE guys...the carbs are simply superb.

The rear carb was a real dual quad carb off a Chrysler which IIRC has a slightly bigger bore. The front was a mutt carb of a Packard or Buick from a single carb application. You can always tell because the lid will have the holes for the choke rod shaft JB-Welded. Interestingly some dual quad applications had both chokes operational.

Not a cheap way to go (we won't even talk about matched 'real deal' dual quads) which is why many run Edelbrocks or the like. Plasticman has a nice less expensive setup on his '62 which you could PM him about. The problem you have is the intake manifold...that bore size isn't going to work for non-WCFBs. Its the classic figure-8 winters aluminum intake. Not worth a ton of money and easily swapped out if you have to.

I'd say wait until Jim is done with your F/I setup or else do a quick rebuild on your tri-power. No need shelling out another $2Gs for a temporary induction system.

Got nothing for you on the generator -- those are big, ugly, and in-your-face...even if you could relocate it lower somehow you would lose the period look you're going for I think.

Therein lies the problem. The accelerator arms on non 2x4 wcfbs are different than correct 2x4 wcfbs.

Is it a problem or are the arms just different but will still work? I believe some of the early ('55-'56) WCFB carbs had different arms than later carbs.

I've read all the comments and I'm having a personal problem trying to decide which I'd run if it was my car, 3x2, 2x4, FI. In addition to functionality when properly tuned/synchronized, any of the 3 would be perfect on a 32 5 window! I love 'um all!
Hundreds of thousands of WCFB's were made back in the late 50s-early 60s for many different auto engines. My ONLY concern would be to locate a generic pair with the same throttle bores and same jet sizes.
And yes, the throttle levers were different, BUT, close enough to permit using an original (or repo) 2x4 linkate setup by simply drilling a hole(s) as needed in the lever. Back before the Civil War days, I ran a pair of mis-matched 2x4 WCFB carbs on a 283 in my 51 Chevy. When I bought the 56 Vette, I swapped them over to it and eventually rounded up a pair of correct matching 2x4 WCFBs which I ran until building the existing FI.
So I'd say, ANY of the 3 will be right in place.
And speaking of generator mounting, here is how the alternator is mounted on the T-bucket. Fits snugly between the frame and the front of the engine.

Tom,

The T-bucket looks awesome. It must be a blast to drive.
Who's alternator bracket is that one? It does take the alternator out of view.
Out of curiosity, what is your fan off of? I've got issues with the diameter of the fan I was planning to use as it will hit the lower rad hose connection.

I've given this a lot of thought over the last few days and with the era I'm trying to maintain, I may just leave the generator mounted where it was and run the car without hood sides..... its kind of a shame to cover up the engine anyway.

I specifically bought the T-bucket for TWO reasons: FI and 4sp. And a plus was that it has the 55-64 style rearend----------------which I build almost blindfolded!
Not only is it a blast to drive, but it is scary as hell!!!!!!! I LOVE IT!!!! Ya really gotta be careful.

The alternator bracket is after market and attached to the 2 lower (55-57 Chevy style) engine mount holes. Works super. The upper brace ( actually lower) is simply generic generator/alternator adjusting brace.

I fully understand having the side engine covers installed, BUUUUUUUUUUT, exposing the engine (ESPECIALLY the one you have) would be pure cool. So, it's your choice.
