Do you plan on running it at the track? With a good 60' time you should get some outstanding times.

Thanks for the props man. It helped to be starting with a strong runner. The good headers helped too.

Nice numbers. How much were the heads? I wonder if Don up here in MA would be interested in building a similar combo......

Very nice results! That powerband seems to really wake up after 4k. Any general duration/lift specs on that cam by chance?

That's debatable. They're good for keeping the guides intact though.

Great heads from WCCH,they really come on hard up top

sorry about the spike-the tq was 441.67
I keep coming back to this thread.

What were the heads milled to? did you flycut? I think this is the highest heads/cam street ls2 I have seen.

Nice numbers and results. Impressive in consideration that it was a 6.0. And Shawn, you KNOW I like the L92 heads as well. What's the engine going in?

The cam is a mid 230's low 240's cam.To tell you the truth i was really unhappy with the end results.I was hoping for a little more low end out of it.
Yes,it has great power up top but the big port really sacrifices low end tq.
I got another cam i'm going to run in a similar ls3 we're doing in a week or so.I think it will be alot better.

If somebody wants this exact cam,i can sell them for $405.00 each.just let me know

weird looking power/torque curve. howcome it follows the first /old curve till 4k rpm than power just surges.
