F0921A F = Flint Engine Plant 09 = Month 21 = Day A = 235 (1957 thru 1962) or 230 (1963 or 1964). You'll need to find the date code to determine the year and the casting number to determine if it's a 230 or 235.

I know the 235 and 230 are physically different, LOL (poor choice of words by me). I should have said the only way to date an "A" suffix 6-cylinder engine built between 1957 and 1964 is by looking at the cast date code. Mike B
