Need some expert help.

I am a new Unimogger. I am the proud owner of a 1967 MB 404.114. I am looking to upgrade the M180 motor to a M130. From reading through the forum (still reading) I believe that I need a M130.925 engine. I have a line on a possible upgrade engine, but it is a M130.980. Will it work? What does the ".980" or ".925" mean for getting everything to line up? Or does it matter.

Any help would be greatly appreciated.

The M130.980 engine is from 280 SE (w111), it is with fuel injection (M130.925 have carburetor) and it has CR=9,5:1/output 160 PS (M130.925 has CR=7,8:1/output 110 PS).

Hmmm... Interesting! So based on this info it would appear that my M130 which has engine block no. 130.923 was transplanted to my 404 from a 250 or 250C, but it has a 9.0:1 head from a 280S. I guess my engine is an M130 hybrid!

Huh.
