Pretty positive it was a l36 block

they switched back to the l67 block for the high whp and 1/4 times.

I like my low compression...it's more forgivable and is perfect for mucho boosto. I don't have to worry about having it tuned everytime the weather changes because I'd be knocking...or part throttle knock with a big cam and high compression...which seems to be a big issue on these cars. Talked to Zach about it in Branson last year about it...he hated tuning it. And he was on a GenIII 3.4"

Yup...because the L36 couldn't take what THEY wanted to throw at it.
