I know gm rates the stock lsx 376 motor at 450hp. Reason i bought this motor it was cheap at 4k for it and it is great for my procharger down the road. Anyways here are some pics of my current setup.

I recently dyno tuned an LS3 480 HP crate motor with a manual transmission in a Porsche.
It put 443 to the ground.
I expect you will see around 400 At the wheels with the Auto if you can lock the converter during the dyno session.
