I had an older gentleman give me a 1957 2 door ht last Saturday to get it out of his garage after 35 years of setting. All orginial as far as I can tell.
I mess with pre WWII cars so I’m pretty much a ‘pilgrim’ on ‘57’s. My question concerns the last two letters on the engine. They are ‘FC’. I understand from the internet that these two letters mean 283 c.i. (F) and 4 barrel (C). If this is correct then it is not all orginial as it has a 2bbl Rochester with mating intake setting on the motor.
Thanks.

Welcome to the site.
4 bbl engine cars had dual exhaust and the fuel line from the tank ran outside the frame. Link to 4 bbl fuel line.
You might also look at the casting date code on the manifold and engine to see if they slightly precede the date of the build. Link to build dates.
The manifold could have been replaced with a salvage yard manifold at one time.

Unfortunately, the engine casting number and casting date code are difficult to see with the engine installed in the car. However, the one check you can make easily enough would be to find out if the engine is actually a 57. See if it has side mounting holes - 3 holes in a triangle pattern on each side of the block. 57 is the only year 283 which will not have these holes.

The model year is on the engine stamp pad along with the F and C. Link to codes.

Using the link, it tells me the car was produced in Baltimore on Dec 3rd, 1956. The engine number is T1121FC, which would be Nov. 21st. It does have dual exhaust and no mid engine mounting points. Still a mystery about the FC. If necessary, finding a 4bbl intake with correct carb will not be problem in my neck of the woods.
Thanks.

The partial VIN (which includes the model year) in the engine stamp didn't begin until quite a few years later than 57. I'm thinking late 60s, but someone else here will likely know the exact year.

The date code in the engine stamp on earlier engines gives you only the month and day.

Your research confirms that the engine is highly likely to be original to the car. My best guess is that some kind of problem developed in the past with the original 4 barrel. Whoever was the PO at that time had access to a 2 barrel carb and manifold for significantly less money than the correct replacement 4 barrel would have cost. The decision to swap was purely a matter of economics.

Some also switched from the 4 barrel during the 1970s fuel embargo, with the (thought) that the 2 barrel would give better fuel economy.

Thanks for the reply’s guys. This seems to be an active forums which one needs when there are many questions to ask. I mostly build low production pre WWII cars. Asking question about a 12 cylinder flat head (yeah, I got one), gets very little response.
I pulled the plugs and squirted Kroil oil in the cylinders for a couple of days. Looked to turn motor by hand with the flex plate but darned if I could fine an inspection plate on this all steel housing power glide. Nothing like the aluminum housing units I’m use to. Jumped it with spare battery and engine turns over fine. Know the gas tank is cruded up and maybe the fuel pump, I’m going to hook a gas can to the carb and maybe it will start. Wish me luck!
