I know it sounds like a hell of a lot of CFM (1700), but they really work well believe it or not. Remember, I've got extra big intake valves running the EDC heads that are ported and match the 427 mid-riser intake. I've got some decent sized exhaust valves and the EDC's are matched to the FF427 Sanderson headers. The torque is fantastic and it revs really quick too. I get through the gears pretty fast. Not bad for stock without NOS or blower.
