Well, I tried to go by the rules and post in the correct section, but apparently that is not the way to do it if you have an LT-1.
My engine is done, (well, except for small details I keep finding and fixing). I was just wondering what type of power I could expect. Not that I can change anything at this point, but hey, that's the way it goes.
Basically, besides going fully forged, it has a H/C/I upgrade, along with methanol injection and a boost pressure increase. If you could give a guesstimate, I would appreciate it.

I say near 500rwhp depending on the heads, cam, and intake combo.

They are all listed in the link; I didn't want to make the post twice and waste space.
They are fully tricked out LT-1 heads - ported, 2.02/2.60 ss Manley valves, CC 918 Beehive spring kit, CC ProMagnum rrs, ARP studs, CC custom turbo cam, Edelbrock Performer intake, 58 mm BBK tb. Everything is port matched and gasket matched.
The person who built the heads does it for a living for the Menards Racing Team. Great guy, really knows his stuff.

Depending on the cam specs, at 12 pounds of boost I would expect over 500 at the wheels.

In that case I would expect over 500rwhp easily. I made my earlier statement based on the fact that alot of porters don't know that much about the LT1 cylinder head.
