Looks like the numbers are cast and not stamped...

 

try this method to figure out what year it is. It is a "late model", since it has the separate bellhousing.

The ones stamped on the back right intake surface can be deciphered here...... Mark

 

Thanks for your insight I've checked out these sites before I just can't read that last number or letter just not clear enough would the marking be anywhere else?
