I have analysed the cast number when I first got hold of Muscadelle, and could conclude the cast date of the engine block to be 22 sept '65.The engine casting date is located on the lower right hand side behind the starter. Your should see this Ford part number "C5AE-6015-E" in raised letters along with the casting date. The actual engine assemble date is actually in two places, on the mounting surface for the oil pan and not visible unless the oil pan is removed, and as I described above, by the distributor.
The actual production date of the car would be 07 okt '65.
Engine blocks were cast, then allowed to cool outdoors for a couple of days (occasionally a month or two) before machining and assembly.
