Default LS6 heads/fast90/cam

Throwing this together for a friend, figure I would get your opinions.

Fast 90 combo
Cleaned up ls6 heads
Comp 232 234 598 610 @114
prc springs
comp tit ret/locks/pushrods
ls2 chain/pump
power bond UDP
1" 3/4 headers
3" exhaust into a magna flow 3" single in single out muffler
150-200 plate system

Power number guess for motor/spray?

I had my previous set up with the same cam, ls1 intake, stock ls1 heads and it made 380 rwhp on the motor with a turbo 350, 3300 converter and a steel ds on slicks, made 521 on 150.

I'm thinking this set up will make around 440 motor and 600 on the spray on 150.

really depends on how "cleaned up" the heads are.

with a GOOD set of ported heads i would say 440-450 with that setup...but milder heads could easily cost you 10-20hp.

the intake might be too big for the smallish heads and the medium cam. kind of an odd mix.
