Allis WD engine build

[dink]

looking to rebuild my grandfathers old WD but I need some extra ponies for pulling. I don't want to go too extreme as we still use this tractor to rake hay and haul wagons.
what can I expect to pay to have an engine built for me, I really don't have the time to experiment with different setups.
any input would be helpful, as well as reputable builders. thanks in advance

What state and what do you pull dead weight or transfer sled?

To keep the tractor useable for your work for it, about as far as you should go would be to install a WD-45 Crankshaft and a 4 1/8" Gas piston/Sleeve kit.
Might need a WD-45 Cylinder Head, also..
Probably adds 30% more power..maybe more..
You will still be using 87 octane gas and the engine will out-last you..!!

as far as I know(what dad remembers) it was rebuilt once before with the overbore kit(don't know about the crankshaft) and it has the "tall" head. is that the WD45 head?
located in eastern Ohio, close to Youngstown.

Put a stock E Gleaner combine motor in it. plenty of power to pull, an easy swap, and still very useable on the farm.
