some impressive dyno numbers today. 06 GTO M6: unported L92's, unported L76 manifold, pacesetter, no cats, 222-224 .566" lift 112 lsa.
and for the naysayers on this board here is a 01 camaro SS with forged 347", TSP 2.5 5.3 heads, MS4 cam, long tubes, single 3.5 in. exhaust, a4 converter locked. same dyno, same day, right after the gto got off the dyno. this numbers are very realistic for a these mods, and maybe a tad low.

i have had one car with ported l92's, way ported l76, alot of compression and a 239-244 cam put down 504 rwhp, but all in all what i see usually is the manifold is big restiction and all that happens is when you run a big cam i you kill low/mid power/torque, but you dont really pick up much more upstairs, because the manifold really restricts it to about 6200 rpm +/- few rpm, so the camshaft really doesnt get a chance to shine, that is my opinion

Outstanding, thanks for posting that! I'm actively planning my L92 build right now, & was planning on using a "little" cam just for driveability reasons. It's really nice to see that it's possible to get nice power along with it! 
Also, thanks to 66deuce for sending me a pointer to this...
What kind of exhaust was on the L92 engine (or did I just overlook it)?
(That combo would pull really nicely in my lightened 'Bird...)
