Which T-case is more desirable? Stronger?
I have both an LT230Q out of a '99 DII and a Series III T-case out of a '73 SWB 88".
I'm leaning towards the LT230 because of the gearing: 3.32 low, 1.22 high. I would also be converting to part time w/ the BCB Off-Road kit if I decide to go this route.
I also have a Series III T-case. From what I read in books I'm guessing it has a 2.89 low, 1.148 high. Are these numbers right?
The vehicle that I'll be building is a '61 Series II 109.
My plans for drivetrain (in the parts collecting stage right now) are D-60's front and rear, an E350 D-60 for the rear (for the offset) w/ hummer wheels to get the track width back, NV4500 tranny, and either an Isuzu 4BD1T or Cummins 6AT? 6BT? diesel. Leaning towards the Isuzu for physical size and weight vs. Cummins.
Another question (and I searched everywhere) what is the difference from a SAE #3 bellhousing pattern vs. Chevy 90* V-8 pattern? Is the bolt pattern the same and just clocked 10-15 degrees? I've read all the Cruiser Diesel pages and really haven't read a definitive answer to what the differences are and what engine comes w/ what. I think the Isuzu and a lot of the Cummins are SAE #3. Are the Dodge NV4500's SAE #3 then? I'm calling Advance Adapters on Monday to see what they say.
I also know that some of the Isuzu NPR trucks were optioned w/ 5.7L's. Were the tranny's swapped out also? One of the pages mentioned a factory Isuzu part for tranny adapters. Was this to adapt a 350 (5.7) to an Isuzu tranny or to adapt an Isuzu motor to a Chevy transmission. Any help or insight....
