Hello
when i was 15 i bought my w123, my dad helped teach me how to do a conversion. i was given a ford 3.0 from my at the time best friends parents. since then it has been reworked and is being supercharged this winter. its feels pretty well balanced and has given no problems in seven years of use. if you want more info just email me. we had to make all the mounts, relocate the ecu, make a drive shaft, ect.ect.

the only thing to go was the starter motor. ford~$56 mb~$200
so as a college kid this helped out a bit.
