Bad *** ! Have you any experience with the 4.30 gears ? I have a 8.75 with 3.91 & was going to spool it but I also wanted to run a 28-29 inch tall tire & my cam is a 3400-7200 range& I should run 3800 stall minimum I'm told
I personally love the 4.30 gear but if you want to get in the 9’s you may want to up that stall some. It’s still streetable with a good transmission cooler.
