360 vs 383

My '69 383 Super Bee was a lightweight bench seat coupe with a 4-speed and 3:91 gears. The only options were sure grip, power steering with a cooler, and a radio. It ran pretty good, but when I put on headers, Crane Cam, lifters and springs, Edelbrock Torquer and a 750 double pumper I dipped into the 12s with 8" street legal cheater slicks. Revved to 6500 with no trouble. It probably would've run a better time if I could have driven worth a darn.
