Street build or Race? I'm diggin the TQ curve. Nice n flat and over 400 ft.lbs from 3500 to well over 6K!!! That thing should move pretty well, and keep pullin. That would be a phenomenal street motor, and probably live forever. I say spray it at the track and be happy! Nice build.

Thanks guys for all the feed back.
It is a M6 for those wondering.
Additional specs:
Fidanza alum. flywheel 13 pounds
Stock rear end w/ 4.10
cam specs:
.610, .619 with the 1.6s but since the valves were hitting piston the 1.5s are on there. So im not sure of the duration and lift now. I need to whip out the cam card.
Static Compression is 13.1
I need to get back to the dyno and work out the timing. I logged the last run of the day and realized I was getting knock retard. i had upped the timing from the previous dyno visit and forgot to dial it back. Currently timing sits at 36,35 @ 95,100 MAP from 4-6500 rpm. Its pulling about 2-4 degrees of timing at each rpm interval although my knock counts are not increasing. So basically, the pcm's command to pull timing is actually more than the amount of factory base timing put in it. So, I think theres more power and torque to be made once that is corrected.
