i want to run a 454, but im not sure what cam to use. i have 2.73 gears (maybe higher) i dont want to go through the hassle of changing gears. it wont be anything exotic. kb pistins (9:1 +-), a cam, an intake and headers. i also wanted to know if my th350 and 8.5" 10 bolt wil be up to the task. the tranny has a shift kit, and the rear will soon have a posi. this is going in a 79 firebird, are there any weird thinga about swapping in this engine other than the tranny bolt pattern? thanks for the help guys.
