Well, if I ever get a response to my inquiry about an SM465/208 combo, I may have to make that decision. I already have the SM465/205 combo in the truck. The pros of the NP205 are obvious, indestructable (in my case) and will last forever. Pros of the 208, IMO, are that parasitic loss should be less (better economy, maybe quieter too, but who cares), floor is already setup for it (I hate cutting holes), better low range, and is pretty strong as well. (from reviews. Although obviously not strong like the NP205, more than strong enough for my use I think) With a 350 being used (Somewhere on the order of a 350hp/375ftlbs motor I'm planning it to be), 95% on-road use, and with my off-road use being what I consider "light" anyways, I'm thinking perhaps the 208 wouldn't be so bad? If I were to get the SM465/208 combo, I would be able to re-synchro, -bearing, and -seal the 465, as well as replace the chain in the 208, before install, so not much vehicle down time. The one thing I *don't* like about the 208 is the (as stock) inability to just remove the rear driveshaft to move the vehicle if necessary. IMO, since a u-joint can go at ANY time, thats almost a necessity. Never really paid attention to the slip yoke eliminator set-ups, are they cheap enough that with all the rebuilding expense that I would incur at this point, that would be a viable option? Other problem is that the 208 could be screwed up internally as well....if it were, am I correct that the 465 with 208 has 32(?) splines and the 205 one has 10, so the 465 wouldn't be a direct interchange either?? I could do my own output shaft swap, but that would mean more work tearing both of the 465's down... I know its false economy in reality to say "better mileage" when all the potential savings will be thrown down the drain in the acquisition of the 208, but I figure the SM465/NP205 already have 25+ years on them, and really will need an overhaul while I own them anyway. Thoughts and opinions are welcome, thats why I ask.
