I have an 81 300D (non-turbo) with a blown engine. Research online has shown
me that this is a '617.912' engine, common to the following models:

78-81 300CD
77-81 300D
79-81 300TD Wagon (only listed as 617.912 in 1 of the 3 online resources I
saw)

some questions:
1. Do I have any other options other than the 617.912 engine? there are
other 617 series out there, would these fit with minor mods? (complete list at http://www.thebenzbin.com/chassisEngine.html)
2. Can anyone recommend a good source for used engines? I remember last year
finding an online classified/board of some sort that listed engines by
mileage, all were good used compression tested engines. cant find it for the
life of me now.


thanks,
jamie
