I have a BBC camshaft, and I don't know what it is, can someone help me out? Here is what I have come up with so far. The only numbers on it are 3597 1025 N1. The first lobe measures 1.537 from top to bottom, and 1.200 wide, and the 2nd lobe measures 1.560 from top to bottom and 1.243 wide. I was told this is a solid lifter cam. Can anyone help me find out what I have??
