Ok so I did some digging through my notes. I came across a couple of numbers. The big one is 509. I know there were some books mentioning a MP 508 and 509 cam that were pretty nasty. The 508 is listed at 248.5* of duration @ .050" lift ground on a 108 LSA. Is it possible that's what I have? The guy I bought it from called it a 509 cam, but the 509 for the small block was a circle track cam from what I remember reading and pretty rare. From what I've read the 508 is a pretty nasty cam.
