I have an MD with a bad engine(as in unrepairable).And a (parts) 400 with a good engine and bad transmission/rear end.The plan is to roll the complete 400 engine,side rails,bolster on to the MD. I'm not going to buy any 'conversion' parts.Simply modify what is there,or even make some parts.I may even have to modify the 400 tin work to 'blend' in with the MD fuel tank.I also have a junk SMTA.I don't care if it is even close to 'original'(LOL),I just want a useable tractor.Probably take most of the winter working part time in my 'spare time'.LOL
 
I did something like that this spring.I split a late 51 M at the clutch housing and married it to 450 I had outback with bad motor and made a usable tractor that has a fast hitch.Scott
 
That's what I did 25 years ago with my MD. Block was broken and couldn't find an MD engine so used one out of a 400D. I did swap flywheels and put the MD one on the 400 engine. Works great, no modifications required.
