I have seen a 3-71 put in the HD5 which is the same rear end and such, slightly shorter front than the 6 I think. Clutch may not bolt up. If a dozer should be easier than a loader. Engine may move back toward operator slightly but I think it is doable.

You will need to find a clutch assembly like the HD-5 uses. Output from the clutch to a driveline. The HD-7 engine bolted to the transmission bellhosing and the clutch was on the transmission input shaft. No driveline in the HD-7s.
