500" 440.........Scroll down to La Roy Engines.
The 2011 AMSOIL/Mopar Muscle Engine Challenge, Part 2 - Mopar Muscle Magazine
Oh heck...check out the HP Engines entry on the same page. It is a 406ci 400 that made 608 HP. Forgot all about the Hollis Page entry.
If you can also get to the 9 pictures, the broken rocker shaft belongs to the 'Prism Racing' 400 block entry. They were winding it to 8,000 rpm while I was standing next to Billy Godbold of Comp Cams and he said, "You hear that? The valvetrain is screaming in agony!"
Aaaaaand boom...........
I think they still won the contest though.
