I have never had much luck using the casting number, nor the stamped pad numbers, so what year and where did my 292 come from? [/b]Stamped pad number: FO 7111BG block casting number:3921970 date code number: CON2 F248[b]--I can only figure out it was cast June 24 in 1968,1978, or1988. If I take off the timing gear cover and look at Leo's book I should be able to get the right decade from how the timing gears are lubed--but, I don't want to disassemble anything on the motor 'til the project can move under it's own power. and I'm certain a wheel don't fall off or worse...Help me ...please?

This is interesting. Your serial starts with F0, and you do have a designator on the end, which looks correct.

This page says your casting is a 1963-1976 292.

I think the leading F could be for Flint. Unfortunately much of the casting information only goes up to 1962 and your engine is pegged to be from 1963-1976 and the casting pages only cover up to a 261...
