Joey, a bit against popular opinion, my research shows you are right, with the way my engine is set up. Yes the 750 works well , but if you plug my specs into the CFM math formula, A 650 cfm will work very well and like you said, have better throttle responce. If I were going new, It would be 750 CFM for future up-grades. I think that since the 650 cfm carb is such a good buy, that is what I will give a try

Thanks all, your opinions are valued.........................MO

smaller carb should give quick throttle response with that combo

Anyone running a 650 CFM carb. on a fairly mild 440 engine?
I have a great chance to buy a Holley 650 CFM with dual accelerator pumps and mechanical secondaries with replaceable jets in the secondarys It is the 4250 series carb. There is a lot you can do to tune this carb. My limit will be about 5-5500 RPM . Non ported heads, about .475 lift cam, dual plane high riser intake.

Any significant difference between a 650 and 750 CFM on this engine?...........................MO
