Just want a few bits to back what I am thinking. Engine GM Goodwrench 350, 4 bolt main. Stock. 74cc head running roughly 8.5:1 compression ratio. Will be doing a cam change when engine comes out and freshening it up. Looking at the Edelbrock Pro Flo EFI (750 CFM) and the Edelbrock Performer Pro Flo EFI (1000 cfm). Would the 1000 cfm be overkill to the engine?
