Default How much of a boost from LS1 to LS6?

Look what I found under the tree!


I'm swapping my LS1 for an LS6 crate motor (2004 cam). How much of boost should I expect at the rear wheels? You can see my LS1 numbers and bolt-ons in the sig.

The crate motor came with the LS6 clutch assembly attached, which surprised me. I guess I have an emergency spare clutch now. I thought about selling some of the parts I won't use, but I'm not sure it's worth the hassle for what I'd get for a stock clutch and exhaust manifold... I'm keeping the harness, computer, power steering pump, alternator, and a/c from the LS1, and renting it to a friend who races an ASA car for a few six-packs of beer...

360-380 whp would be my guess with those bolt ons you have listed also.
