Ty (LoudSS) picked up the car today to get it inspected and we'll be finishing up the tuning after we have 1000 miles on the motor. He will be in here later to let you know his impressions

read the post, he gave rough specs already:
Mikey: Cam is proprietary for now but the lobes are based on our Dominator series cams (55mm). Spec if 244/250/113 0.612 / 0.610 ICL = 110*

I wonder why the Vette with the 408 is making less power with a very similar setup.

So cam, compression, intake setup (Ty's lsx is ported/port matched for instance), tuning all make a big difference in power. Internal components setup, pistons, lifters etc.. also have an impact, as does valvetrain setup (rockers, springs, etc...). Although the impact can be smaller, if everything is speced out and setup with a plan from the start, then you get a combination that really maximizes the power potential. Heads porting also varies hugely, but in the case of two cars with AFRs its going to come down to the other factors if there is a large variance in power.
