Complete 450 engine. The governor or governor control arm needs changed. Choke rod bent to work on the other side of carburetor if using the 450 one. If using a ignition drive housing and not a engine driven hydraulic pump. You need a housing from a SM or a M from sometime in 1950 or newer unless your M has one that new to fit the 450 bolt pattern. Housing will have a cast # ending with R1 to fit the 450. Run a PVC hose from the 450 valve cover to the air cleaner intake pipe side opening. Unless the M is late enough to have a 12 inch clutch and a liftall housing to clear a 12 inch clutch use the M flywheel and clutch. If not using a hydraulic unit in the clutch housing or a late housing to clear a 12 inch you can use the 450 flywheel but need the 12 inch clutch for a SM. Wouldn't recommend using a M distributor on the 450 engine if it still has 40 degree advance parts in it.

I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
