Power valves or no P/V
I know I'm asking a lot of questions and I dont meen to be a lot of trouble I'm just trying to get it all right. I know some of yall been doing this a long time and yall know the do's and dont's a lot more than me. so for Drag racing only is it a plus to plug the power valve and jet it up or is it just done for insurance against back fires and blowing your power valve out.
Thanks Andy
