Hoping someone can tell me why?..My brother-in-law purchased a Super M LP on Saturday. It is serial number 128??. This makes it a 53'. It has a 248 block. I have not heard of Super M's having 248 blocks, only 264 blocks. Did they use the M block in the beginning with larger pistons, or what?? In the same barn is a Louisville Super M. Serial number 505???. This is also a 53'. It also has a 248 block. This one is locked up and has poor to no tires. I was interested until he said he wanted 1200 for it. 1 last thing, has anyone seen a Super M LP sell. About what is it worth. Paid 2000 for this one and drove it on the trailer. Thanks, Lee

As D Slater says it is a replacement C248 -- why the previous owner used a 248 instead of a 264 is anyones guess. 248's can be built to 264 specs.

If the block has C-248 cast letters on the side its a replacement block. Date code probably won't match rest of tractor.

Lee, Post some pics of this ol girl. from all angles, up fairly close. There are too many possibilities as to why it has a 248 engine.
Need to see the tank too. Looking forward to the pics so we can be of further help. There are some of us here on the Boards that know a lot about these ol LP SMs.
Later,
John A.

I will try to get some pictures. Time is not on my side this week or next. Working 2 jobs to feed the kids and support my tractor habit. Maybe Sunday I can get some.
Thanks, Lee

As far as I know "M" '39-51 is 248, "SM" is 264, also SMTA and 400. 450 G or D was 281.
