650 or 750 cfm. carb??

Quick fuel 750 should get the job done now and when you upgrade..Demons are a pain to deal with,i will never buy one again..

I'm curious as to why you think Demons are a pain to deal with? They are almost the same carb as a Holley or a Quick Fuel. 4 corner idle, power valve, double pumper, seems the same at least. Never had a pain dealing with mine.
