powervalves
seems a lot of people dont run them on there drag cars, was told at least, I should block back powervalve and jet up 6-8 jets, was told I could run front to clean up off idle mixture. I like to get a lot of input so give it to me, for dragracing do you all plug powervalves or at least back ones on a double pump. This is mainly a bracket race only, streetlegal blazer very lil street use!!!
