Thanks for confirming that T350 and TH350 are the same.
My cousin helped me determined my rear end gear ratio by jacking up the back end, and counting differential output turns to wheel turns. We came up with 4:11, but a lot of people keep mentioning 4:10 gears, so I got confused on that, but it sounds like they are both basically the same.
This calculator says 2950 rpm at 70mph with the 4:10 rear end, and 2500 rpm at 70mph with the 3:52 rear end. (33" dia. wheels). This seems to answer my question, but it doesn't factor in the gearing in third gear of my T350 transmission. If I had a newer 200R4 or 400R4 transmission with overdrive, the engine rpms would be lower, so I'm assuming the transmission high gear matters, or is their a minimal difference?
Thanks, JP
