This is a very interesting one, kept C6AE-L heads on it as they were correct for the restored police car. However, they are an emissions head (small port, low exhaust), nothing was ported or blended, and the compression is a true 9.96:1. Cam matched fora 3.00 C6 4 door actual police cruiser. Should be a very fun "highway pursuit" car!
Stangman:
So basicly a stock rebuild with a cam. 3.00 gear and a c-6. That’s what I had in my mustang when I first got it with a 427. Had the B cam I believe the one with 306 duration, man that thing would pul forever. Idle at 800 in gear. Nice build Ross.

Thanks, its a nice runner, certainly sounds fierce!
