A buddy has a couple sets of gears that I can buy for a 14BFF and D60. I want to know if either of them would be good in my Suburban. I have an 89, TB350, 3SP Auto, and I will be running 35's this summer. I use this truck as my DD and I also tow with it regularly. In the future I plan to install a few power addon's like a cam, intake, exhaust and if I am really froggy some kind of forced air induction. With all this in mind... what gear ratio would YOU recommend for this scenario?
