Block casting code: looking aft the code should be cast at the block/starter motor interface at the 2 o'clock position
Date code: should be below the block code and will probably be impossible to see without removing the starter
Engine serial number: should be stamped or cast into the block about 4" back (mid-point of the starter) about 2 o'clock position. Ford reman block shown below
Note:
These numbers are a PIA to get to
In all likelihood they will be covered in grime
Try having the car on a hoist (engine/exhaust cold) and taking photos with a good mobile phone
Try using a mirror
Last resort - take the starter out
All of this is possible if you are a skinny bugger like me and have a hinge part-way between wrist and elbow [
