Is there a COMPLETE list of all the purple cams anywhere anymore? There were a lot of numbers including all of the oval track stuff. I would think that cam is one of three or four. Either the .533 hydraulic with some wear, the .528 solid with some wear......who knows? I haven't the faintest idea how to figure hydraulic or solid other than a complete mapping with a degree wheel to see what the ramps look like, OR send it out for mapping. IF I was going to do the latter, there's only one place I would send it. I would send it to Jim at Racer Brown. He could map them and tell you for sure.
