thanks for your advice i was thinking about that exact cam. i know the heads are small but do you think i would bennifit from 456gear,carb,cam and converter upgrade and only buy heads if i dont hit 10s. i really like the numbers on that cam. the rear end is 12 bolt 31 spline axels c clip elim. im not a tranny guy but im confortable with th350 put a few together. im shooting for mid 10s
