Austin,
1960 was the first year Chevrolet put a 'zero' in front of the month, so your engine ID number breaks down like this...
F = Flint
04 = April (1959 and back just used '4' for April)
09 = Day
J = 235 with 3-speed transmission
I also believe the D22 casting number is your date code
D = Month (April)
2 = Day
2 = year (1962)
If I'm right, your engine was built one week after it was cast.
