650 or 750 cfm. carb??

CFM......cubic feet per minute, a measurement of the velocity at which air flows into or out of a space. I was talking air not fuel... the fuel can be adjusted.

I'm not going to argue with you on this. Run the small carb I really don't care. I would take the larger carb (750) on a 408 come race night everytime. Don't believe everything you read.

CFM is volume of air not velocity.

We are talking about a 360 not a 408 and we are talking about a street car that might go to the track once in awhile. I will take a carb that will give me the best response in the rpm range I am going to use it the majority of the time and for a 360 that won't see the high side of 6000 rpm that is something in the 650 to 700 range.
