The short answer is yes. The M115 flywheel will have twelve crankshaft bolts; the M180, M114, and M130 engines were supplied with both six-, and twelve-bolt crankshafts. If you are fortunate, the donor will be twelve.
Other issues to be addressed are pilot bearing installation, transmission mounting position in the chassis (farther aft due to longer engine), drive line length (shorter), shift rod length (shorter), speedo cable length (longer), and matching of
imbalance of the flywheel.
