So my '51 Super C blew a head gasket and I was not aware. It won't start anymore, has spark and fuel but no compression. Not sure what is wrong internally but it is going to get a complete rebuild.
Now me being who I am I can not leave well enough alone. I see that the "standard" complete rebuild kit takes the pistons to 3.25" taking it to a C-135 engine vs the factory C-123 with 3.125" pistons. The sleeve bore is 3.43" for the lower section OD.
I see several people put a C-153 engine out of a combine/504/etc in as a complete replacement, then you have to bore for a pilot bearing for the clutch in the crank as well as rework the hood/water system/fan etc.
The C-153 is the same basic block as the C-123 but is a sleeveless block. Does anyone know if I can bore the C-123 to the same piston size as the C-153 and just run it as a sleeveless block? What about rods and the crank? I would think I could just change the pistons, maybe have to change rods, but the crank should be the same. I still have more research to do before I start on this project, and get the lawn furniture out of the other bay of the garage so that I can have room to tear this one apart and rebuild it.
Anyone done this or know anyone that has?
I am going to start poking around the antique tractor pulling circuit around here and see what others have to say. I would really like to keep it factory on the outside since I typically show it at tractor shows and don't want the purists to get their panties in a wad.
