The only possible "problem" would be the cruising rpms of the DZ tranny.
Stock tires yield 4800 rpm at 70 mph. Maybe some people can live with
this but I doubt I could. If he has a DM tranny 70 mph is almost 4500.
This drops to 4000 at 70 with a waterboxer tranny.

I am familiar with Frank's opinions in this regard and I respect them.
The lower gearing provides more power at a given road speed. He lately
seems to have acquired an interest in obtaining a DK air-cooled tranny.
These give about 3700 rpm at 70 mph.

I think most people would want to get lower highway rpms than the diesel
tranny gearing provide. It is not required though. That still leaves the
mounting issues of the older tranny position versus the Tiico engine
mounting position.

tranny, diesel DZ, diesel DM, and air-cooled DK tranny among them.)
