Advice to newbies and their tractors

HI all,
First let me state I have a late 1948 Super A that I am in the process of restoring. The engine that was in this tractor was a C123 (not marked on the block anywhere) and had a water pump. This confused me as it was supposed to have the C113 engine, or was it? I then learned that it could be either one. Down the rabbit hole of casting numbers and date codes. Apparently, my tractor had a replacement engine at some point from a 1953 model. The only way I was able to tell for sure that it was a C123 was the size of the cylinder bore. C113 had 3" bore an C123's had 3 1/8". I rebuilt it to use the uppower kit of 3 1/4". Anyway, my advice for anyone starting out on a similar path of restoring an old tractor would be this. Make yourself a spreadsheet and record every casting, serial, date code, and part number stamped that you can find on the tractor. Get ALL the manuals for it. Then take ALOT of pictures before you start, I mean ALOT, of everything , down to where every clip and bolt goes. Find a restored tractor and take pictures of that. and good luck. OH, and use the forums!
 
later blocks will take the 3 1/4sleeves measure your old sleeves and if the od at the seal measures 3.343 the block will take the 3 1/4 set I just bought a kit last week 347.00 from G@S in VA now to get to work.
 
The C113 engine has an up-power rebuild kit that would make the C113 go from 3" to 3 1/8".
The C123 engine up-power kit went from 3 1/8" to 3 1/4". I believe they also came with domed pistons.
These are listed in the parts manual.
