The GT3071 should be able to make 350whp on pump gas on that motor given the cams and head work. Maybe add a re-plenumed intake manifold, then you should have no trouble. Should be able to do it at about 17psi.

Here is my dyno from when I had a similar setup. Biggest differences are I had a 2.1L stroker, and oversized valves.

If the images don't show up for you, get the photobucket fix for either chrome or firefox.

These were at ~20psi on pump gas with water injection, but also at almost 5000ft. So roughly 3psi was compensating for the altitude. Others with similar setups have made similar power at sea level and ~17psi.
