I don't know, it's so hard to say with so few people running a setup like that...

actually i will revise my previous number didn't realize you were still running ls6 intake. I'd say 450.
I put down 435 with those same heads unmilled and a little smaller cam w/92 Fast intake. Now this number was with a restricted ypipe setup so my TD's opened it up a little more.

430/390tq is my guess. I just put down 425hp/400tq with a similar setup but with a fast and stalled auto.
