Very stout numbers for a bone stock motor. Bet it's a blast to drive.

Great numbers! The LS2 can take a good amount of abuse with the correct tune. Ive done many Procharged LS2's in the 700+ RWHP range with no issues.

yes..more power then we would suggest, but the customer wanted to push it and we did so 
I do agree with a proper tune these Ls2 have proven to live with some big #'s.
