I have a (89gta) 383 hydraulic roller motor with 10-1 cr sportsman 2 64 cc heads and it currently has a 222/230 duration @.050, .509/.528 lift with a th400 trans w/2500 stall and a edelbroch rpm performer intake with edelbroch 750 carb I was wondering how much horse power this combo would make and what other type of cam I could change to to get more power about 450-460. Any help would be appreciated for cam swap
