I couldn't find an exact breakdown of the code you have posted, but I did find a "TA" code that was used for the '65 230 and the '66-'68 250 used in 2wd C10 trucks with manual transmission. It seems that your code is missing one character, as it should have letter for the plant code (F is usually Flint) then a Month/Day code, and lastly, the application code. You might check for a casting date somewhere on the block or head. I can't really give you an exact location on that generation of Chevrolet 6, as my knowledge is more with the earlier 216/235/261, but you might look somewhere near the starter.

235 and 250 used different block castings. 230 and 250 used the same casting and we're first installed in 1963. 1962 was the last year for the 235 in these trucks.

Take a plug out and look in the cylinder, if the piston has a flat top it's a 230, if the piston is dished it's a 250.

307 V8 pistons are a drop-in fit in 250 engines, and they're flat tops.
