PP#2

Hank Rotroff, Jeff Campbell and Jack Canady all had wicked fast AH 81/82 PP engines. The flywheel side crank seal is a bear to replace, and the early thin cylinder castings were weak near the base, and the early three bolt mount crankcases were also weak. The later PP 82's weren't bad with proper porting, a boost port, head cut off and replaced with a billet head with ears for tie rods to hold things together. I've seen all three guys engines run very well against 820 Benders. You have to know how to gear them so they take advantage of their different power curve. Hank Rotroff was a master with the engines. I had one of the later ones when I lived in New Mexico, but I didn't have access to the machine tools I would have needed to make it run well Here's a pic of Hank's '61 Fox with dual PP 82's Ted
