There are 4 cyl Yanmars that fit, and I believe the 4 Cylinder Cummins (maybe 240 cubic inches--same bore and stroke as the 5.9L 6 cylinder) will fit, too, if you have enough "headroom". Beaucoup bucks, though. A fair number of 28 Bertrams that started out with small block V-8 power have been re-fitted with diesels, you might try googleing "28 Bertram+diesel repower".
