We recently had the pleasure of installing our Speed Inc./PRC heads and cam package on Anthony's 05' GTO. The mods consisted of PRC Stage 2.5 cyl heads, our SI6 camshaft, FAST 92mm intake/stock TB, long-tube headers no cats, 160* thermostat, and a Yank SS 3600 torque converter. The car made 472RWHP and 414RWTQ!! We were very happy with the results!! ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)

Very nice! A buddy of mine is in the process of doing his 06 Goat (6-speed) with Mast heads, custom cam, Fast 92, and pretty much the same bolt ons as this one I believe. He's at like 440 rwhp minus the heads right now, and hoping to hit the 500 rwhp mark very soon.
