Last 455 used 455HO heads I ported and a set of 455SD con rods (knew the people out at HO Racing in Hawthorne, CA well, bought a bunch from them), along with a Edelbrock intake and a 1000 thermoquad carb. 4.56 gears in the rear and 1.65 rocker arms with a RAIV cam. It would RUN. Guessing mid 11's. Could lay down rubber from one power pole past the next one. Tires didn't last long.
Had another Pontiac with 3.23 gears. Stone stock, but long winded. At speed those power poles went by as fast as fence posts. Only did it once, to see just how fast it was. That was enough. Not going to push my luck!! My guardian angel was tired by then. Oh, those were the days:bigsmyl2:
