My cousins Srt-4 stock is really fast...but I think you can take it if its a stocker. Cuzo added the mopar ugrade for his turbo and did some trans work and well les just say on street tires his fastest run to date is 12.91 and thas on pump gas no add ins. From what ive been told those blocks can handle an ass of boost and around 2k you can cut almost 3 sec of your 1/4.
