So I just bought a farmall super A that was mostly rebuilt from what I was told but the engine is not the original from what I can tell. It is stamped C 123 and has the numbers 366204 R3. Can anyone tell me more about this engine and weather I need a water pump or not? Thanks in advance for any help, it is much appreciated.

You have a Super C block, so it should a water pump, does it have a dipstick also ?The ones with a dipstick was a stationary engine, they used them for shallow well irrigation, carnival rides etc !!!

By memory there should be a machined pad on right side of block about 1 inch below head and 3 or 4 inches from front with model and serial numbers stamped in. If a
replacement block there is a good chance of no stamping. Some one with more knowledge respond please. Leroy

That is a later part number than would have been originally installed in a Super A. But it is a correct later replacement for a Super A block. This wasn't the original number for a Super C either. But it is a correct later replacement for a Super C block too. Except for the last few built with larger bore sleeves and pistons, the Super A didn't come from the factory with a water pump. Although a water pump can be back fit to an earlier Super A, it was rarely done, even when increased bore sleeves were installed during an overhaul. It is unlikely that you need to do it either.

The engine number is stamped about where Leroy said. Look directly below the #1 spark plug and very close to the top edge of the block. Something stamped there will probably tell you whether a new replacement block was used or if it was a used engine what model tractor it came from.

As a later replacement part, it needed that for compatibility with the later tractors.

Is the number FFA 204312 or FAA 204312?

From what I can find, I think FAA 204312 was built in June 1947, if that is the tractor serial number.

The only way I see that engine number make sense with that part number and date code is if it was a replacement block that got stamped when it was used in the field.

The date code translates to January 7, 1960, which is reasonable for that part number. The 204312 engine number matches a 1947 Farmall A, not a Super A. I don't know why anyone would stamp that number unless it was the engine or serial number of the tractor it was going into. The original post said Super A. Can you verify that? What is the tractor serial number? I believe the original engine number at that time would have been prefixed "FAAM". If the replacement block was stamped in the field, they may have stamped "FFA" rather than "FAA" by mistake.

One more thing, it probably wouldn't have made financial sense to put a new block in a Farmall A in 1960 or beyond, it barely did for a Super A. At that time, the bare block was about $200. Add another $60 or so for a S&P set. There would be a bunch more needed to finish putting it together. Meanwhile, you could buy a nice, complete tractor for about $400. But it appears that is what happened here.
