farmall M

[4 bottem]

What cubic inches do you end up with when they run these tractors without the sleeves, and do they stand up.

I am no Farmall expert, so take this with a grain of salt, but I was told that the standard M motor without the sleeve will accept a piston from a 656. Can anyone verify that claim?

Depends on what year block you have and how good block before you start.You can do more with latter blocks becuse there is better metal in castings.
