Christmas is coming early for me. Since this is a significant investment, thought I'd get some feedback from the pros out there... mostly on gear ratio choice
First off, for gears, I wish I hadn't put a 1.41 hi-gear into the transfer case. I want to run a 36 or 37" tire. According to the Ashcroft calc, 4.12 gears would put me at 2766rpm @ 70mph with 36" tires. 2691rpm for 37" tires. For consideration I have a heavy vehicle and a Kent H180 cam (a bit milder than a crower)
Should I go with 4.12 gears in the diffs, which should be just about right for 36 or 37" tires (assuming the goal is 2700 rpm in high range), or should I put 4.37 or maybe 4.75 in? If I had 1.2 gears in the transfer case, 4.75 would be perfect. But realistically, I don't see myself switching back as it's a lot of work
Second, diffs. Originally I was going to rebuild these myself (I've already done the engine and transfer case), but the cost, time, no downtime, and benefit of just letting Ashcroft rebuild it for me seems like a no brainer. I think I'd save like $200 tops per diff to do it myself.

Might as well peg it!
Core return.. probably not going to happen...
