School me on Stock Eliminator?

Thanks for that, Bill. It sounds a bit like current grudge racing. I guess fewer cars being available then made it easier to police the rules? I can only imagine that "the nature of competition" has led Stock to where it is today. -The more NHRA allows, the easier it is to police. Back-cut rings, dipped heads, combinations created out of thin air, that's just the tip of the iceberg, as you know.
The partner I had on a D/SA '71 RR in the nineties started in the late 60's at Atco. He had a 65 Catalina w/ a 421, and he enjoyed getting every last bit out of the stock parts. That was always my attraction to it, too. Of course, it's too easy to modify stock stuff, and on a local basis (and divisional and national), we both know a lot of stockers weren't per the rules.
I started following it in 72ish, when the rules were no headers (open manifolds ok), no slicks. (I don't remember exactly) My neighbor had a 6pk RR that got me hooked on Stockers and Mopars!
