I got a stock Q-jet from a Buick 455 off of ebay for $70. Would this be good for a 383? I'm just looking for any info on this carb, thanks.

Yea... i think they are bigger than most other Q-jets too, cause that was the biggest engine to get them before the smog era wonders, like the 200hp 454s.

Would it be easy on gas too? Is there any more info I might need? Thanks,

a well tuned quadrajet is HARD to beat for anything less than a race car. small primaries for economy, huge secondaries to balance out the small primaries, and = BIG FLOW, almost 800 cfm.

very easy to change metering rods, there is a book on quadrajets that i highly recommend, from HP books, the only downside to them (read: reason one isnt on my truck) is the fact that you have to use a spacer or a special manifold.


they rock, its just that simple.
