So I have an 87 w150. it was my first truck has a 78 360 and a np435. Id like to give it a sort of new lease on life and add a nv4500 so it'll be a little more drivable with overdrive. I know Id need a new tcase. I'm also aware that gasser 4500's are hard to find. Is it at all possible to rebuild a diesel trans to accommodate the 360 that's in the truck? Also what else would the swap require? Any help would be great thanks!
