Edelbrock Heads for 318

If the longer stroke motor stays together at super high rpm's like a short stroke motor can, then yes it make more power. But you are talking big $ and thats only posslable now cause of the high tech stuff avaiable now. I am not sure how much stroke those grand prix cars they have over seas have but they rev over 12,000 rpms now. Thats why they sound so different. I do know they cost well over a million dollars. Back to our great little world, I agree that a 360 for us with today's gas is the best way to go if you want the most power and diverablity. Those NASCAR 9-1 motors would not be good on the street, you look like a freak idling at 3500 at the stop light. The motor needs high compression to idle low with a big heads and camshaft.
