[QUOTE="davidd, post: 41841, member: 1177"] I think that Eddie may be correct. Steve runs in the Production class because his bike is not legal for the Vintage class. You have to use original cases, muffs and heads to be eligible for the Vintage class and he is using Irving-Vincent cases. Also, the "Gas" that is allowed at Bonneville is leaded super high octane. There are several blends and octanes available, but the idea is that if you run in the "Gas" designation (as oposed to "Fuel") that everyone has the same advantage by using only mixtures that are available on site. By contrast, Marty ran his blue bike in "Class C" which was restricted to pump gas and 8:1 compression pistons. 147 mph is quite an achievement under those conditions. The John Edgar bike was a stock Lightning, but they ran high compression pistons and fuel and thus it ran as a Class A machine. David [/QUOTE]
