There's a VIN decoder on this site:

This assumes of course that your engine hasn't been swapped.

yup, well not meaning to sound like the dummy that I am I still would like to know what the "M" in 351M means.
And Derherr65 did you mean 351 M or really mean 315M. I'm kinda new here and would like to get the right directions

The 351 engines have letters after them because they can't be distinguished by dispacement alone. 351w = windsor, 351c = cleveland, 315m = modified. Most of the references I've seen(this site, chilton manuals, npd catalogs etc) refer to it as 351m. You can fairly safely assume that 351m, 351 m, and 351 modified are all the same.
Incidentally the 400 usually is not called a 400m or 400 modified. However if someone calls it that it's still the same engine.
