Dyno & Bench Racing Forum - H/C power guesses?

Ok, just wondering if anyone could give me a good estimate on how much power i can expect to make on my combo im putting together.

currently has...
2002 LS1
1 3/4 LT's
ORY
SLP loudmouth exhaust
25% UD pulley
LS6 intake
Ported Throttle body
NGK iradium plugs
msd wires
No a/c
no air system
K&N filter on a custom intake tube
ls7 clutch
40k on motor

ford 9" rear with 4.11 gears
aluminum driveshaft

car is a 1988 trans am GTA

what im adding to it now...
Ported by BES 853 heads (no flow numbers)
MTI X1 cam 232/228 595/572@112
stock ratio full roller rockers
918 springs
hardened pushrods
ls2 timing chain
TUNE

430 is my guess

430 is my guess

that would be sweeet, then id do the fast 90

i dont want to be the party pooper but i think 430 is a bit high. my guess would be 399. but im a glass half empty kind of guy. but the way i look at it is you have a engine making 315whp or so stock, so full exhaust and a cam would have to add over 100whp. my guess is it will net you about 70. but ehh thats just my 2 cents.

I have headers, no cats, underdrive pulley, ported throttle body, ls6 intake, loudmouth exhaust, Custom intake.

and the cam will be ported heads, cam, roller rockers, springs, ls7 lifters, pushrods gaskets etc.

then why are all the other bolt on ls1's with an mti x1 cam making about 400 to the wheels?
