He's posted here a few times in the past. His other car and truck projects are pretty interesting, too.

I subscribe to his YouTube channel and watched it last night.
Did he ever mention pushrods? Would they be the same length? 370hp from a worn out iron headed 7.6-1 comp engine ain't to shabby.

I didn't notice any mention of checking pushrod length or changing them, but that may have been edited out of the video footage.

Yes, 370 net (hopefully) HP from an low compression iron head engine with lots of blowby is impressive. It will be interesting to see what they do to cure the blowby, probably new rings.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
