I have looked everywhere for this block code and cannot find it anywhere.The motor is in a '73 ford pick-up and the numbers behind the starter are EOAE-D5C and just below that is 18 and 4D3O the base of the dizzy is in line with the base of the intake so I know it's not a windsor. It has 6 bellhousing bolts. The stamped code just below the driver side head on the front of the block is 2180. I am stumped thanks
