Re: 3969854 block question

Try tapping that casting date of D 7 7,and cast part # of 3969854 gently with a metal object to see if anything like an epoxy cracks off..I have seen this before as an attempt to deceive.
If nothing happens,focus on that blocks pad stamping.
Do the broach marks & stampings look authentic through a Linen tester?..I don't see an IEG suffix used in any Chevrolet BB applications.
