2004 GTO M6 - LS3 Swap

took the stock low miles Ls3 short block out of my 2010 camaro (817rwhp on turbo setup). Put the shortblock with new bearings in the gto. Car has the following mods:

GM CNC LS3 heads
BTR .660 springs
BTR stage 2 cam (225 238 113lsa)
Mildly ported LS3 intake with 92mm TB
kooks 1 7/8 LT's
Flowmater 2.5" catback
LS7 clutch/flywheel

pretty mild build... I am guessing 465rwhp/425rwtq

Thoughts?

On this same dyno I did 460/430 with AI heads, 235/231 115 turbo cam, ported LS3 with 102mm TB back when the short block was in the camaro.
