Dan, what about Page 61, paragraph 2, which states : Coupes and Sedans produced from 1949 to the current model year, not meeting the criterea of the Classic Catagory, must compete in the Modified Classes Category. I read the rule you speak of, but to me, the rule on page 61 should supercede basic engine requirements. I understand the division decisions, but if the EFI rule takes precedence, it means that a racer is penalized for running a carburator or mechanical fuel injection. Something doesn't seem kosher. I had a 1984 Olds Cutlass with a factory carburator. It seems incredible to me that a vehicle can be found to be non-complient for running mechanical parts which are less efficient than what the record holders run. Maybe your techs at Speedweek are confused on this too, as we talked over my class change and the reason for it while teching in. I realize, however, that there job is to tech you in, not interpet the rules, but the way I am reading you now is that I either have to remove the data recorder and run as a Classic, or run as the car is now, for Time Only. Either way, it doesn't make sense to have to add electronics to step up in class. Thanx for your time. Bob
