Hey: I recently pulled a 351w out of a 68 FB and was curious about it. the casting numbers are:

D4AE-6015-AA 4

http://users.zoominternet.net/~Natedogg01/casting.jpg
With the smaller numbers in the lower corner being 4K28.

There is old ford blue block paint on it... underneath the coat of black. Which would lead me to believe it is early but you can never be sure :p

Any help with telling what 351w this is would be greatly appreciated. Early/Late. anything...etc.

This is also a "heavy" block. In 1975 the 351W's lost about ten pounds of cast iron weight. Unfortunately it came from around the main bearing webs where it added some strength. While they may not compare to a late model "MotorSport" or "Sportsman" block, these blocks are still popular with folks planning on using superchargers, nitrous, or (ahem) turbochargers.

I'm going to keep it... I just wondered where in the years it came from. I do know that it is the standard bore size. Im leaning toward a 408stroker kit though.
