I'm too lazy to look up specs, so what are the specs on your cam ??


Do you have SAE numbers ??

Looks good to me, of course this is my first LS1. over 100 ponies for basically intake, exhaust and a mild cam. I'm sure with a more agressive cam and heads it'd break 400 easy.

Nice numbers man! That's a pick up of 22rwhp and 21rwtq from without the cam...

Are those numbers corrected or standard? With a u/d pulley and some 1.8 rockers hello 385+!

I had the car since the weld in muffler and it's came a long way!

That is truly a baby cam. Not much more lift then stock, just a bit more duration on the intake, and a good bit of added duration on the exhaust side. Total sleeper for a cammed car. Good **** man.

The numbers are post tune...keep in mind everyone that the ls7 clutch increases the power lost through driveline just a bit...

If you mean sleeper as in quiet and non-letting off the hint of cam that is way off. This cam is a monster sounding cam.

Look up my buddy jbird and look in his sig for his results.

nice numbers if you got a set of heads and the pulley dont be surprised if you pick up 60 plus rwhp the 98 heads are not complete junk with a stock cam but when a larger cam and ls6 intake is in the mix they rob you a good amount because they are acting like a bottleneck.

I hate to bring back an old thread but why does the torque drop of so quick above six grand? It looks like a very aggressive cam under the curve but not much of a top end performer. The HP looks good though, could someone explain that to me?

most people think lift has to do with the idle sound. thats all in the duration/overlap & LSA.

Correct me if im wrong, but it should have 11* overlap. That should lope hard.
