I'm about to bid on a rebuilt q-jet on ebay, price is right. This is the great description.
PART# 7028244. THIS IS A FACTORY REBUILT 4 BARRELL QUADRAJET. ALL WE KNOW IS THAT IT FITS BUICK AND IT HAS A DIVORCED CHOKE.
Any reason why I couldn't use that on an Edelbrock performer non EGR?

I'm thinking the q-jet is a spread bore carb (the secondarys are much bigger and wider than the primaries). The performer manifold is a square bore (same width primary and secondary). You can buy a spread bore to square bore adapter, but they're about 1" thick if you have hood clearance, and you create another place for a vacuum leak.

There's also this one I'm very interested in.
800 CFM Rochester Quadrajet, great for a performance improvement!
You are bidding on a professionally rebuilt Rochester Quadrajet. This carb has 0 miles on it since rebuild. This carb is listed in catalogs as a direct replacement for Non-computer controlled GM 305 used in Chevs, Buicks, Pontiacs, and Olds during this time, as well as Chev 350s. This particular carb was originally used on a 1981 Chev Suburban with the 5.7L/350 cu. in. engine. If your carb uses a front fuel inlet, you will have to re-route the fuel line to use this carb.This carb uses an electric choke
Carb number: 17081291
Date Code: 0201 DDY
72 jets
51M primary rods
DR secondary rods
This carburetor is a 800 CFM carb, as it has the larger 1 7/32 primary bore as opposed to the 1 3/32 of the smaller q-jets. This carb is also a non-feedback carb so it would be an excellent choice if you are planning on getting rid of your feedback controls.

Yea, I'm aware of the adapter situation, and I should have plenty of room.. It goes on my 360 that's currently in my '89 YJ... If I have to, I'll cut a hole in the hood... :lo1l:

Would it be better to use an open plenum adapter or a 4 hole??
