the last 460 swap i did I used the mounts that came with the engine and fabbed some new frame brackets. 460 vans have rear sump pans and an oil filter casting that you can pivot around to different angle, the van oil filter casting will fit on any engine that uses the ph 8a filter. I think some Mopars also use the : Ford :filter. Some HD 460 Vans also have a factory engine oil cooler.
