I have an edelbrock performer, square bore, 600 cfm carb. with this work well with a strong 455 with the poston alum intake? or should i find a good rebuilt Q-Jet?
600 CFM, forget it, way too small. The stock Q-jet was 750, and 71 and up 455 carbs were 800. Don't even think about using that 600, waste of time. And the Poston S-Divider, you'll need to do some tuning to get the best out of that manifold. Never really heard anything great about it, but I hear it likes carb spacers.
thanks larry, i'll ditch the carb w/ the 350. the engine is coming w/ the intake, so i guess i'm going to have to make it work or go w/ an edelbrock performer intake. any place to find a rebuilt Q-Jet 750 or 800 CFM?
I had a chevy 427 in my 72 chevelle and used a modified 750 holley, it ran real strong but needed more air. I put a 600 to get accross town to pull the heads for some porting. It had TONS of throttle response. from idle to 2000 RPM NO ONE COULD TOUCH ME :grin: after that it farted every engine swear word in the book. Go larger! 800 Quad sounds good. 750 Holley can work.
Try the Quad shop I think they sell rebuilts. T/A performance also sells them. Try a local junkyard and look for 71-74 Electras maybe you could find a cheap one but would still have to rebuild it. The Q-jet is still the best all around street/perfromance carb for our cars.
