I concur. It seems like this should have been posted as a resolution to that other (original) thread. Doesn't really address the perspection/concerns back then, does it?
Or state if a problem was found.
It's always nice to see/read resolution.

You might have left a bit of power (and torque) on the table (with the choice of that [TPIS?] cam with those heads), but it's a solid build that'll have great longevity. If you have a Dana 36 auto, it's also a choice match for longevity. GREAT distribution of power throughout the powerband too!
Did you install that cam "straight up"?

See its not as bad as you thought although youve spent a lot of time on it
perhaps due the the torque curve not being "peaky" you just think its supposed to be faster or feel that way.
should be a solid 12 sec runner with no problem.

Base ls1 yes, 2002-2004 Z06 very close in power, and they have less weight.

I think it has a few peak hp left in it. It got real fat up top. I think someone explained to me that the air/fuel ratios will vary dependent on the MAF flow at the time. On the street it was high 12:1 AFR. Different on the dyno. But in the right ball park.

I'm done poking around with it. Until I blow it up at least. Then I'll do a 395 or 396 whatever it comes out to. I think it'll last a long time though. This motor has 106k on it.
