Default is it reasonable to expect 390-400hp from this setup?

the cam is
gross valve lift .567/.571
duration at .050 224/228
lobe separation 112
timing at .050 open 4/50 close 40/2


LS2 heads, comp 7.4 rods and patriot springs
long tube headers
underdrive pulley

on an otherwise 2000 MY engine

has an LS7 clutch to hold the massive power I probably won't be making, lol.

with the 4.10s and IRS, id say you're more towards 375-390

are the LS2 heads stock?

didn't realize it was an auto. That will put a dent in your numbers but can help you at the track

i think it is an m6 but has the 3.90 cogs instead of 4.10 since he said he has an ls7 clutch for all that power he won't be making. anyways i'd say you should be in the area you are hoping for, maybe 385 or so may be closer but you can never tell.

it's not, it's a t56 that's a completely different issue since the motor is going in an rx7 chassis.
