I'd look for a complete Casale C-500 since they are stout and usually more commonly have 4% to 15% gears. That way you may not have to change your rear differential gears. Plus, the C-500's are quiet and don't rattle when idling like the split case v-drive. Jocko
I have a C-500 with 22% gears. With a th400 it would give you a nice overdrive ratio. Dan, Casale sells a lot of drives to the offroad racers, they seem to hold up good. A C-500 would be my choice also.
are you selling the box? i already have a tranny(th400) and a motor(454) just lookin for the v-drive box. gearing wise i am already pretty sure i am going to have to tear into the axle beacuse its a dualy two speed rear end.
