Greetings: Does someone know how to determine the CFM of a stock Quadrajet on a 1970 Cutlass with the Rocket 350? I found some numbers on the carb, but not too sure what they mean. Any help would be greatly appreciated. And while I'm here, could someone tell me the max CFM I should be looking at with the 350 engine. Thanks in advance....

 

Q-jet were only made in 750 and 800 CFM...your 70 Olds will be a 750, but few flow that as delivered from the factory. Hope this helps.

 

Thanks Dan.... I'm looking to replace it with another Quadrajet and found one that has been rebuilt / tested. That one was is a 750. Wanted to make sure that I would be replacing it with a correct one. Thanks again.........
