Engine Help identify this 302, pictures included

Not an explorer timing set or accessory drive.

Looks like F150 timing cover and sensor for the 4-post trigger wheel.

On the block head the header, there is a part number cast into the block, as well as a date code as to when the block was case. Also, the rear china wall where the blue gasket in the pic may contain a partial VIN stamp if you clear it up well enough to see.

If you can get those numbers, you can make a good guess as to what this block is out of.

Also, on the cylinder heads, there will be a date code cast in the rocker valley somewhere as well. Ford date codes are 4-digit, with a letter in the 2nd spot. Something like 2A13. Jan 13, 1992 (or 1982, or 2002)
