However the main issue is the huge sump cavity that hangs down from the engine which would reduce clearance under the rear of a Haffie. In discussion on a Landrover forum a member indictated they once had a Haflinger with a boxer BMW R100 engine in the back. He said that mating it up to the haflinger gearbox was not a big issue and it ran very well. With a double the power of a Haflinger and a 6500rpm redline the Haf had a top speed of over 70mph but if not careful the gearbox would not handle the power.
To get around the clearance issue he removed the sump and replaced it with flat plate and converted it dry sump - apparently easy. The BMW oil cooler was mounted under the front bumper in a neat arrangement and with the system full of oil everything works fine.
Unfortunately he did not have any good quality pics of the arrangement - here is one from the rear with the lower engine just visble. And a pic of the front with the oil cooler - again poor quality as they are scans of old happy snaps. Thanks to Rory for the pics.
While I would not ever consider converting my vehicle - if I acquired a wreck that was not worth restoring, then yes. But then maybe a Subaru dual range engine, gearbox and transaxle to replace the Haf unit
