351W ENGINE BLOCK CASTING NUMBER?
Hi Y'ALL. 
Just bought a 351w and I've been told it is a 1984 Windsor from a f150 4x4. I looked at rear of block on driver side above bell housing and I found this number: OEPB40387. Can anyone help me decipher this code so I know what I'm dealing with? I'd really like to know what it's telling me in detail.Thank you.

There should be another cast in number along the pan rail, that will be a better number to use. If it is a 84 block it should start something like E4, E being eighties and 4 the year.
