There has to be somebody out there who can custom grind an exact duplicate of a GM cam.? Unless I am missing something, it doesn't seem that big of task considering all the CAD systems in use, CNC machines etc.

I had always heard that the only company allowed to copy the original GM grinds was Crane, so the other companies had to *tweak* their versions enough to be deemed legal...as a mater of fact, I was speaking with a guy at a performance wharehouse trying to track down a 143 and he mentioned the vary same thing. And us Pure Stock guys have found out the hard way that other blueprint cams aren't up to par with the GM/Crane units...
