The man who finished 2nd in BR points (and by all rights won the title the year before in the pure stocks at CMP in the same exact car) was running a car that was more stock than 95% of hte cars out there, a home built chassis (that was damn near a decade old). And with a bone stock crate 602 (at least in 2015).
The cars at black rock are nothing special and wont obliterate CMP cars, like everyone seems to think. The cars that were fast, will still be fast, and the back markers will still be back markers. Nothing will change except a few extra cars in the mix.
