Default Best guesses?

Hey guys, new here but ive been lurking in the shadows for a while.

Ive got an 02 SS SLP that i just finnished buttoning up a head and cam swap on. Its going to the tuner on the 17th and i was hoping i could get some rough guestimations on what i should expect so my heart doesn't get broken. Lol

Ls1 5.7 6spd
Ls6 intake
Smooth bellows
Slp smooth lid and ram air
speed engineering long tubes (catless)
flowmaster 80
243 heads, eps 660 dual springs with fresh valve job, port and polish and milled 0.008"
eps cam (.603/.604, 112 seperation, 12.4 overlap @.050)
eps trunions in factory rockers
7.400 PR
Mellings oil pump
msd wires

Stock rails, injectors and fuel pump but i am currently on the hunt for 36# injectors as per the tuners request.

Anyone care to hazzard a ROUGH guess? Itll be run on a dynojet dyno.

LS1 5.7 in stock form out of Z28 or SS made 325-335 fwhp and the ZO6 was what 405 fwhp, I don't see where your cam, heads and exhaust will wake that motor up enough to deliver 400 rwhp but I guess it's possible, especially with an M6 spinning the stock driveshaft and rear end.

Did find this thread to give you an idea of what stock produces.
