I thought I read (but can't find the post now) that the low dyno was done with like 15psi in drag radials, and the higher dyno had 30psi in the same tires.

Don't know if that's worth 57rwhp, but it's got to be worth something.</edit>

Oh, come on guys, ET heads aren't that good, don't you guys know that it's all hype? There's NO WAY they could put out good numbers, it's just hype.
...
Glad someone brought this topic up. One more notch in the belt for ET's proven performance.

How did he manage P/V clearance with that cam/head package. Seems like a close call to me!

I don't see that cam producing any p/v issues with that setup depending upon where the ICL is. If that car pulled that far chances are the ICL is very late and would clear just fine cause of the wide lsa.
