The reason is that i race on a 1/3 mile clay oval,and its supposed to be a stock division.but we can get away with bigger injectors,computer tuning,intake,and maybe a cam if it doesnt push over 180 hot off the track.i know a lot of people dont know what im talking about because they race street..but im in second gear wide open from drop of green to checkered.my sst chip is set to 12500rpm so i will never hit the rev limiter.i know a lot of other racers get bigger injectors.so i was wondering what i can get with out going all crazy
