Any guesses?
He wants to make 450 and I think it is possible depending on the heads.
I know the damn headers aren't the best but he dosen't want to switch.

It'll be close with the C5 driveline, but like you said, depending on how the heads perform, it should make it.

Thanks Beast.
You have a stout setup yourself.
What kind of power did you make?

Haven't been to get the tune yet. I still have to get exaust, then go to Futral for the tune. I'll post up then.
