I'm just starting the process of resurrecting a dirt oval race car my grandfather campaigned in the '50s and early '60s. I'm going through the garage of vintage speed parts, and I've come across a cam shaft. Gramp's and Dad's memory is that it might be the "Eliminator" cam … it eliminated either the competition or your engine … but they can't recall for sure. They also think it may be a "3/4 grind" cam.
Is there any way to tell what it is? I've only found a few marks on the cam, and I'm not sure if it's been re-ground or not.
There's a narrow "X" on one end, "GM 9 3" (I think) and "36604 4" There's a groove between the "9" and the "3" and between the two "4"s, so I can't tell if there should be another digit there or not.
If the numbers don't tell me anything, or if the cam's been re-ground for different performance, is there a way to look at it, or run a diagnostic of some kind?
I'd like the motor to evoke the memories of the high-performance Stovebolts the family used to run, but I've no desire to be melting pistons and all the other issues they had when they were building full-bore race motors. I'd like peppy, lumpy but reliable.
