Ok, I understand - I guess. I am planning to build my next Yenko deuce as a Certified Pure Stocker by following the rules laid down by the PSMCDR crew in Stanton, MI. I've been to several of those events, and I really enjoy them. I think there is a distinct challenge to get the most out of a pure stocker by putting the time and effort into the buildup that GM couldn't do within their mfg parameters.
I think that what you are saying though, is that if I get all my ducks in a row by blueprinting everything to GM spec's, etc... that I might be disallowed as a pure stocker bec/ I'm faster than history? I'm not trying to be a hard asss here, but it sort of defeats the goal of trying to make your car faster! I wasn't around back in the 'day', so I don't have a basis for what historical cars ran - but I know that I (with help) have dramatically improved my own et & mph compared to my own history, and I plan to keep improving.
BTW: If you put me through a tear down, I would pass - but I know that my car will never idle smooth at 900rpm. I think the spec is actually 1000, and the best I can get it too right now is around 1200 - which is just fine since that's my launch rpm sometimes
