You'll want to stick with high impedence injectors...ala factory style. 60# injectors will support the HP level you're seeking. However, just as a point of reference, we finished a project not long ago with a 2004 Cobra, KB Blowzilla (2400 cfm) at 17 pounds of boost tuned out nicely at 577 RWHP. The T-trim at 1200cfm and 8 psi of boost on that 331 bottom end is going to net about about 450 at the wheels. 10 psi will get you in the 475range. You'll need 15 psi to crack the 500 level.
