engine upgrade
Has anyone successfully upgraded C-60 engine to a higher horsepower late model motor? if so, how was it accomplished? I wouldn't think by raising the compression ratio ,via different pistons, this would give more horsepower, only higher compression ratio. Or is it as I expect, "just not worth the expense and hassle"

Never tried it myself, but from previous posts it appears there are several steps to ge the full benefits. The head has to be changed or some grinding done to clear the domed pistons, the intake manifold and carb have to be upgraded to the newer model, and the cam shaft has to be changed. Now that I've scared you with all that, you can get a gain by just putting in the domed pistons and grindidng the spots in the head. If your engine is worn you'll be amazed at the gain just from a rebuild.
If you are not part of the solution,
you are part of the problem!!!
you are part of the problem!!!

Don't forget, increase the RPM's! That in itself probably produces the most HP gain. I don't think the 154 engine provided 15 HP, nor the 185-184 series provided 18 HP. Wishful thinking coming from the advertising department.
The domed pistons are not domed like a hemi. Only a portion of the piston is raised, shaped like a U. Picture 1/4 of the piston is diked for a dam, hardly powerful in appearance. It is not what I expected - I thought it was a damaged piston!

The French Super Cubs increased the horspower by using a different carb and raised the rpms up to 2,000.
IH designers had a higher horsepower cub on the drawing board early on.
It was even called a "Super" Cub. It used a different head ( I believe one from the Cub baler engine.) There were also some other differences. I will have to dig out the blueprints I have on it from IH.

Not to be a poop - it would be easier to just get an A or Super A and, most likely, you would end up spending the same money.
My son and I work on trucks a little and just a few modifications add up quickly. If you were going to do a rebuild anyway - the domed pistons and a little grinding wouldn't be bad. I don't know anything beyond that would be worth it.

Larry, George Willer is in the process of installing the engine from a 154 cub lo-boy into a standard cub. He may be able to answer your questions.

If you can't fix it with a hammer, you've got an electrical problem.
