Those numbers are almost identical to my R5P7 440. I can almost guess what the HP and torque numbers are.

I am curious to what the cam specs are. Wonder how close they are to my R5P7 engine cam specs.

My little 421W8 only left that hard with an unknown coverter and blew up thanks to some interference with pistons and valves. That's another story. I had to give the converter up and never had that luck with any I had built. The engine was pretty much a gutless wonder that ran like stink on the big end.


I will gladly share my cam numbers on an open forum but, can understand if you want to keep those to yourself.
