I am planning a diesel conversion in the future and I'm going to buy a bolt on Ford 8.8, but i need help deciding the gear ratio. It is suggested to get 3.07 with 33" tires for the diesel. but I don't plan on doing to whole conversion for a while. So my question is, which gear set would be the best for both while I'm waiting to get the diesel. I'm trying to only buy gears once, is it possible? I'm running 33s with my D35 i think i have 4.11s right now and its ok, id like a little more power. Also I think i might go to 35s after the diesel swap.
