Slapped this together from a pile of spare parts:  C120 hydro chassis, 8 pinion 8 speed, early round hood rear fenders and pan, late 60s hood, foot rests, Brinly hitch, loaded AGs, 1:1 pulley ratio for 9-10mph. I use it to pull a plow, run a dozer blade, and take an occasional trail ride.
Engine is a late Kohler K321 with big exhaust valve- .010 over, balanced, decked, Chevy LS intake valve cut to 1.65, ported and relieved, custom ground cam, K241 head with extensive work, ported #30 carb, tuned exhaust with Jim Kemp muffler. Its 9.3:1 compression and runs fine on 93 octane, governed at 4000rpm. I also run an oil temp gauge to keep an eye on things.
Lets see some of your 'user' machines!

Duplicolor DE1653 engine enamel- dang near a perfect match to the original IH red

Awesome engine build! I love seeing the old engines being hot rodded, they can make some real power.

The K241 head on a K321 is interesting, does it have a smaller combustion chamber for a compression boost?

@Rustbucket Garage I misread, sorry- engine is duplicolor DE1653 spray bomb. The tractor is PPG #70019 single stage urethane- the equivalent to the IH #50 red- which is the darker of the two.

Yes sir- much smaller chamber. Its a later K321 with the big exhaust valve, I had to remove a lot of material to clear that valve alone, and wanted to have room to unshroud, grind, etc...and still have some compression, thats why I used it.
End result was 9.3:1. It barks!
