Gary NO. There is however some people claiming pure stock that aren't pure stock by the rule book. Example brakes: OEM upgrade allowed not aftermarket! Tim griffeth (sp?) had his pure stock mustang back in the day and switched brakes on the front which then got him tossed out of pure stock and into traditional stocker status. Back to fuel in pure stock. The approved fuel sheet says "pure stock entries may utilize OEM unleaded blends meeting rule book specifications" so we go to the rule book where stock has to remain a dielectric constant of +2.3… pump gas won't have that unless your getting it from down south as they use a different blend. (If you'd like I'll bring my fuel checking equipment). SO when mixed with whatever you want to mix it with, it really goes off the scale. Kinda like me mixing C11 and C25. Stock is a rule book based eliminator if you don't follow the rules in the book, you have a regular bracket car so you should claim the real class your in. Either footbrake or top.....
