I have a decent TH350 from a 2wd, and id like to swap it in place of my 700r4. I don't see much life in the future for the 700r4, its just too sensitive of a transmission for me.
My question is what ill need for the 2wd 350 to bolt up to the np208,My understanding is that the 700's output shaft is about two inches longer than the 350's. So that said, I would have to either get a longer output shaft for the 350, or I would have to bring the transfer case closer to the transmission with a different spacer and move the crossmember? Also needing an extended driveshaft.
Also is there a difference in the output shaft of a 2wd th350 vs. a 4wd th350? Would the 2wd 350 possibly have a longer output shaft?
ORD has some transfer case to transmission adapters being offered now but I didn't see one for this swap. I'd like to avoid having to rebuild the transmission which would take the extended output shaft option away, if possible.
If anything I wouldn't mind finding a np205 to rebuild and swap in along with the TH350, they have a 350 to np 205 case adapter, which im assuming would move the transfer case closer to the transmission which would mess with my driveshaft but that's not a huge problem for me.
As of right now im thinking its not possible to mate an np208 to a 2wd 350, I know the bolt patter for the tailcone is the same its just the output shaft and the total driveline lengths are tripping me up and confusing me
