So since I'm about ready for college, I'm gonna be doing a lot more cruising in the near future. I know that a diesel 700r4 will bolt up directly to the B350, no adapter ring needed (which is actually a step up from the nailhead TH400 Jeep used originally, with an adapter ring)(Why????? Come on Jeep, they literally make a TH400 that bolts to the Buick from the factory, just put the shorter output shaft in
). I know the shift linkage will all work pretty easily, and the TV hanger is going to be a pain to set up. Also with the cost of the adapter for the D20 to the 700r4, while I'll want to have the D20, it'll probably be cheaper and easier to just use whatever Chevy tcase comes with it. And obviously drive shafts will have to be replaced. 60 mph is ok without the O/D, not ideal, but OK (doesn't downshift ever, which is nice IMO), but some of the stretches have a speed limit 75. I'd rather not spin the engine that fast (3200 or so, right at the peak torque) for 4 hours straight if I don't have to.
My question is about the added length. Does that create clearance issues with the gas tank? I was just under there today and it looked like I had about 6-8" between the D20 and the tank, but I just want to be sure. If I do that, it'll be an expensive swap to start with, and I do NOT want to get it half way in and realize I have to modify the fuel tank for it to work.
I'll probably figure out TBI or something instead if the O/D tranny has no chance of working.
Thanks guys!
