From what I've read my motor should be good for 510-530fwhp. As long as I have some good torque #'s I'll be happy. I love 6 spd's Heres a link to my build w/specs

GM rated the otherwise stock but carb'd LS2 motor at 440 HP

A good 35 HP more than the stock FI crate motor. The stock LS2 cam and heads are the same as the "LS6" cam people talk about. the motor in the link has the LS6 heads too (243 castings). I have the motor above with a Holley 750 DP, mechanical secondaries. The open plenum intakes need a pretty big shot of gas from the accelerator pump to keep from bogging. Most guys end up with the 50 CC pump on the primaries.
The DP may not be the best carb for these motor. My idle screws are only about a half turn out. That is with a piece of wire in the idle orifice to cut the area. I wish the carb had adjustable idle feed restrictors and air bleeds. But seems to be running OK as set up.
Check out the thread in the stickies about putting a carb and dist on the LS motor. Lots of good info and specific set ups in there.
500 HP is acheivable with nothing more than a cam upgrade. I have been thinking about a Lunati voodo cam. Seems to be a popular option for these motors. Trouble is the car scares the bejuzus out of me as it is. The LS2 motor also has the LS6 springs that people talk about a lot on here. Although for the voodoo cam I think stiffer springs are needed.
