I've seen older Alisons in school busses,that had 350's or 366/427 BBC motors..so yes,one of those would bolt up--but I dont know how they shift,if they use a modulator or electronic control??..if they used a modulator you could use the vacuum pump and VRV valve like a TH400 on a 6.2 would use..but how to hook it too a transfer case is a good question!..probably have to use a divorced case?..
