Sorry I don't have numbers, but with a small cam (g6xe) and a FAST intake I run 11.25@124 at a DA1400. I'm sure that with a bigger cam (may require flycutting) you will get better results. The fastest Z06 in Hungary runs 11.2@125 on drag radials, with intake, Vararam, tune. Based on that I would say that my car has at least 450 rwhp.

Theres a guy here with a full bolt-on cam only ls2 running running 11.20s@123. From what I have been seeing is that people with this set up have been getting upper 400's and even over 500 wheel.

LS3 heads/intake + a decent cam should get you 475rwhp without too much issue.

He's more than welcome to duplicate this in Hungary at a higher DA and an unprepped track. My DA corrected times are 11.0@126-127 still on an unprepped track. And I have a sleeper cam, some people wouldn't even notice there's a cam in it. Driveability was very important to me. With proper heads and a bigger cam you should see numbers close to 500 rwhp.
