Can someone with a GM parts book (probably an older one) run a cam number for me? It's #12551622 for a BB Chevy. It's supposed to be a Hydraulic Roller, but I haven't been able to find it while searching through Jim Pace or Scoggin Dickey's websites. :confused Thanks a million, if you can help me out.

That is not a Chevy production cam number. All Vette big block cams from 65-74 all looked something like 38899999 or 38699999. Unless it may be some truck cam I would have to say it is aftermarket or the cam for a later crate engine.

Yeah, I think it was a cam made a few years ago. I found a small-block number that was similar, but I still can't verify this one. I think the advertised lift for intake and exhaust is supposed to around .511 @ .050 with 1.8:1 ratio rocker arms. The duration is around 224 degrees intake, but I'm not sure on the exhaust. I need to find the facts on this before I even think of buying it.
