Just use the 74 specs. Like M.B. DOC. says it is basically the same engine til 1980. The changes that ocurred through the years was the addition of catalytic converters in 75 and the switch from EFI to CIS in 76. Also fuel trim control was introduced in 1980 in the form of a frequency valve.

The torque specs are the same on all of the 1971-80 M117 motors & that is what you have!
