4L80 1/4 rear end gearing
Got the new trans installed now I'm concerned with my gearing. 3:89s with 28inch tires. Will I run out in 3rd before the finish line? There maybe more info than I'm giving to determine that so let me know. Thanks ahead of time. Oh red line/rev limiter hits at 7200.

Is 3rd 1:1 on that trans?
If so 3rd should top out ~154MPH.

Yes and thanks looks like I'm good to go. This little mod got out of hand on the budget lol. Glad my gears are good.
