The 300 series IH engine (312&360ci) are about 4 inches shorter than the 400 series (414-436-466-530 ci) In most of the IH trucks there should be enough room for the longer 466. The rear engine plate will bolt up as the blocks are tapped in the same locations. Sounds like a good project. Overhaul kits are avalabe for the dt 466 well under $900.
