Big Block racing camshaft

[Rex T.]

I have an L-88 engine sitting in my garage that has an aftermarket camshaft that I cannot identify. I have not removed it from the engine because I may want use it, but I would like to know the specs on it. Engraved on the end of the cam are the following numbers:
D6207 292/304R8 6567

Nothing else, no name, nothing. The cam has a copper color to it between the lobes and I think it is a roller type cam, sut not sure, as the engine is still completely assembled and I don't want to mess around with it too much until I can identify some particulars. It was built by a well known machine shop in California several years ago, has Carrillo rods, Arias pistons and a Barnes dry sump oil system. Any help that anyone can provide will be greatly appreciated.
Thanks, Rex #8089

That last number should have been 6568. Thanks, Rex

Re: Big Block racing camshaft

the 292/304 stands for the duration and R stands for roller. best i can do

Re: Big Block racing camshaft

I suggest that you put a degree wheel on the crank and measure the intake and exhaust with a dial indicator. You should be able to work out exactly what the duration and lift and overlap is. Based on the numbers it sounds like a large cam which would be hard to use on the street. Good luck

Re: Big Block racing camshaft

Can you simply call the builder and ask him? Have you checked the west coast cam grinder's catalogs like Engle, Isky, Clay Smith and Crower?
