Or could they also be configured as C113 engines?

They were used with thicker walled sleeves in the
later Super A?s at 113 ci displacement. Sam

with C-113 engine SN: 310300 & up the use of the larger displacement kit is possible. Below that there may be a kit with more cubes, but dedicated to
that block. The bottom of the block where the sleeve spigot hits the Oring is smaller in the low # 113 engines. Jim

This particular block does not have a serial number on it. It does have a date code on it of 4-15-X. The tractor it's in has a broken steering housing so I surmise they broke the front of the block and purchased a replacement somewhere along the line. It also has a Super A head (9052D) dated in '47 so there is a possibility they just upgraded it for the additional power.

I wish I would have known this when I had the oil pan off. I could have measured the bore.

Thanks for all the information. I do appreciate it.
