    I’m not either why I was trusting the guy who told me who has raced most of his live. He said it would help me since I have 3.06 gears. He wants me to swap to 3.92 but not ready todo that yet

    The pros use lots of sidewall because they need to stick at 700+hp. It depends on how hard you are launching but it’s a balancing act between sidewall needed, width against rolling resistance and total diameter for final drive ratio.
    He may need to go back to more sidewall with the new converter though. And definitely go back if you go to 3.91.

    Understood, didn't think that he was rolling with the 3.06 gears. I have the 3.91 w/6 speed so I tend to think everyone does LOL
