I have a Gen 2 GTX3576 and it currently makes 521whp on 93. Also there is a guy on youtube called 40RollX,

. Check his comments. I think he is around 670whp with a bigger inlet and built head with cams, but you know how youtube can be.

What other mods are you running? And how much boost? That seems high.

It is a 2.4 stroked at 29 lbs. boost.
