youll probably be ok with the 42# injecs, i would say around 45X rwhp assuming its a T56 tranny and a mid to high 11 if u can drive well. AFRs are very well built heads, bout I would get a lil more compression with some stage 3 5.3L heads.
And talk to Ron at Vengance and get a ported FAST, WELL worth the money!
