It is a late production 351M/400, with a casting date (1L10) of November 10, 1981. It was manufactured during the last model year (1982) that the 351M/400 was produced.

Since the same block was used for both 351M and 400 engines, you have to identify the crankshaft to determine which one it is.

Check this page for more info about the crankshafts:

bubbaf250, about your "can't use a wire in the spark plug hole".
if you measure the stroke and get 4" you have a 400 or a stroked original 351M.
if you get 3.5" you have a 351M or a destroked originally a 400 (which someone should be commited for ever doing).
so what I'm getting at, I agree this is not for measuring the authinticity of the original intent of the block but aren't you getting the answer for what is it now?

ranchero,

The linked page refers to measuring crankshaft stroke, not the block. The issues are the same, regardless of the origin of the block.

The problem is that there is no practical way you can get a reliable measurement. I have seen several cases where measuring with a coat hanger yielded less than 3.5" with a 400 crankshaft.

ctfuzzy,

Thanks for the kind words.

I have lots of data, but little time to do much with it right now. For two years, I've been saying that I'll get to it in the next few months.
