I will be installing a BBC in my '36 coupe. I am trying to decipher the engine code.
The code is stamped just above the timing chain cover. It reads "T1101FCN"
I know the T represents Tonawanda, NY and the 1101 represents November 1. What does "FCN" represent? I have looked through various BBC websites and have been unable to ascertain what FCN means.
My assumption is this engine is out of a 1990 or so Chev SS pickup truck.
Any help?

big al, I found this maybe it will help.
Engine Assembly Date/Suffix Code:
The engine assembly code looks similar to this "T0422TR". In this case the first letter "T" stands for an engine factory Tonawanda, an "F" or "V" for Flint, MI. The next two digits stand for the month of the year, in this example "04" or the fourth month April. The "22" stands for the 22nd day of the month. So what do we have so far in this example? The motor was assembled at the Tonawanda factory on April 22nd. The years are not given. What we have left is the "suffix code" which in this example is "TR". Chevy used one to three letters of the alphabet to code the type of engine, transmission and vehicle into the suffix code. In later years, parts of the Vehicle Identification Number (V.I.N.) were also added before or after the Engine Assembly Date/Suffix code. In that case you might see "T0422TR 1123456789" stamped into the pad on the front passenger side of the block. Sometimes the V.I.N. was stamped into a different area of the block on the flange edge of the rear of the block, near the bellhousing mating surface. Sometimes the stamping is found above the timing cover mating surface on the front of the block.
