I’ll look into it all of this. Thank you for the advice. My only problem is highway driving with 3.91’s. I’ll have to weigh the pros and cons on that. I was already thinking about moving up to 3.55’s... I need to reread your reply a couple times and do some research. Lol
If you the 3.91 your engine will be at about 3600 at 70! Of course that’s with 25 inch tires. There are calculators free online that will give you an approximate
Rpm and some that even include converter slippage.
