This is a JW spec cam made by comp. I ran it for a year but since swapped to something more mild. This is a lumpy race type came. Lots of top end power. TSP 525-10.5 - 246/253@.050 .544/.560 lift. The cam card is in the picture with full specs. The cam is in great shape, comes with matching comp lifters. Located in vt 150 plus the ship. It's pulled and readyto go.
