Considering my back-up option on the rebuild of my 756 gasser - if the cost is close.
I get the impression that a 5.9 is the most talked about repower, but might be overkill for a 756. What about the 3.9L Cummins diesel into a 756 gasser? I think Leamans has an adapter kit that fits both the 5.9 and 3.9 engines.
My thought is a 3.9L might be lower cost as I gather it is not as coveted as the 5.9 ? Also the 3.9L is shorter and with it might fit-up better lengthwise and possibly keep the sheet metal and frame rails original?
Anyone put a 3.9L Cummins in a gas or diesel 706 or 756? I'd like to retain the same PTO hp or maybe gain a bit, not interested in pulling or blowing the rear. Just want a nice haying/chore tractor.
Still of the mind I'll rebuild the C291, but again, if a diesel swap is close in cost, might move in that direction.
Thanks!
