The idea of the additional weight is to encourage drivers to go to the 602 crate.
How far is GM up everyones azz. There are still alot of guys out there running with old used parts slapping stuff together. Ive seen a bunch of these crate motors run well with everybody. The simple fact is, some people do not have the money, including me, to go out and build all new gears, the right carb, and everything thing else you may need just to change to a G.D. crate motor. Limiting horsepower is a proven fact in any racing that the money will be spent on lighter weigh,t more expensive parts elsewhere. I am a big fan of the class BTW! Jon Ripperda
