Manual transmission. 3rd would act as my primary gear, and 4th would be an over drive. That would ratio wise effectively make the 3.54 into a 6.03 or so when using a sm420 3Rd gear (1.7). Would a Toyota trans handle 500 tq, multiplied say 5:1; so effectively 2500ft/lb- excluding shock factor?
I haven't made a commitment to a wheel lug pattern yet, but thanks for the reminder.
As for lift, I know I'm going to have to raise the body some, as well as the obvious suspension, probably raise the engine/trans/ 2nd trans up to maintain clearance. Which will help when it comes to tires, just wanting to keep center of gravity reasonable.
The hopes are to build everything as light duty as possible with out having to deal with breaking stuff all the time.
From what I've researched, the nissan 4x4 transmission should hold up about as well as anything else, those old muncie and np transmissions are torque proof, just trying to fit the rest of the puzzle together. Hard to balance: compact, light, strong, clearance, and reasonably affordable lol
