Is a Edelbrock 600cfm performer too big for a stock 300ci Buick motor? This will be going on a 65 model 4 barrel manifold (cast iron). I know about the 500cfm model, but the 600 is less expensive and seems to be available in reman units also, so if it doesn't drown the engine it would be a less expensive choice. I have searched for a AFB, but by the time I buy a core and rebuild it, it's equal or more money than a Performer. Any opinions or experiences?? Thanks
I would consider the AVS, not the AFB. Like a Q-jet, the AVS has a spring loaded adjustable air valve. The carburetor sizes itself to engine demand. http://www.jegs.com/i/Edelbrock/350/1806/10002/-1
