8.2L 4 stroke tubo diesel in a K30?? Not sure what they weigh. Trans could be an allison automatic and I'm sure there is someway to mate it to a 205 if you don't mind spending the dough. Or maybe there is factory parts out there who know?? Obviously you'd have to adapt some motor mounts. Not too bad there. No computer to deal with. What else... I know some folks hate the 8.2's but the one in my bus runs awesome and that is one big vehicle already.
