Ron I think you are on to something here.
But first, we can leave the LT77 out of it - the whole idea is to skip the transmission. If I wasn't skipping the transmission then getting this right wouldn't be that important - I could use the gears to pick the best ratio while driving
I had no idea the was a part time 4wd kit for the LT230. And a 1.6 and 4.7 gears in the diffs gets me a 7.8:1 ratio which may just work (I need to noodle this some).
What I like about this plan is I could even do it in two phases as well if I wanted to - phase 1 would be just use a 1.6 LT230, and phase 2 would be to convert to part time 4wd and add the freewheeling hubs once I know the ratios are good and I feel like I need the improved efficiency.
As I was looking up the part time kit, I saw people mention that doing this can cause more stress on the transfer case and rear diff with reduced handling and minimal fuel economy gains so it's got me wondering how big of a difference running 2wd would make anyway?
I'm assuming an LT230 is quieter than a series transfer case too.
