I know the Caddy I ran all those yeas was .390 stock and it allowed us to have a .430 lift cam made by Crane. They latter decided to apply the same cam rule to the trucks. I wasn't involved in that decision. Jim

Jim is correct there. As an addendum , The indexes were so soft, in the beginning, in order to encourage participation, it didn't make sense to try to jerk all the the factory ratings around to get things equal..So, therefore ,the equal lift rule.
I'm not sure on the truck deal, but it probably was a similar situation.
That big ol' Cajun fella would know....
