Re: Rpm question
I'm not familiar with that tire size. But now that I know the diameter I'll bet you have 4.56s. It was an available option in a 1/2t but you didn't see it much, especially in a V8 truck. But even going by the prior post, 4.56 is a lot closer to 4.41 than 4.10. And going by the C/10s I've had with 4.10s I don't recall the RPMs running that high.
I'd go the simple route and put a 3.08 rear in. You lose the grunt gearing but you still have granny, if having a low gear still matters. You come close to the same numbers from going with O/D as you do going from 4.56 turns to one vs 3.08 turns to one. Divide 3 into 4.56 and you get 1.52. Take 1.52 from 4.56 and you get 3.04, virtually the same as 3.08s.
