Default 3969854 block question

Had a fella want me to come look at an engine before he put it in his race car as he was told it was out of a Corvette. Block number 3969854 dated D 7 7 stamped EG on the pad with big outlet above the oil filter.EG comes up 66-67 Chevelle but they never made a 854 block untill 69.Thought maybe i read the D 7 7 wrong but i dont see a EG or anything ending in EG 69 or newer in case it was actually D 7 1 ,,any thoughts,im lost or blind?

Is there a Vin or anything else stamped on the pad or oil filter areas besides what you've noted? .

A complete Vin could indicate a factory installed engine....count back the 8 digits from the end for possible vehicle model year. . Are you getting the EG from a complete Tonawanda engine number w/ date ie. T0123EG? . EG is L78 from 66-67&68? .

Heres what we have TC42IEG 7K149839 Doesnt appear to have been messed with and it's been in the hands of racers for quite a few years ,,im just saving it before it becomes their next victim.

It's probably TO421 EG.
That along with the casting date of D 7 7,(April 7th,1967),would mean it was assembled on April 21st,1967.
The VIN# of 149839 is applicable to a January 1968 assembled Chevelle-Elco.That means the engine sat assembled for 9 months before being issued into a vehicle.
That spells out to be a 1968 Chevelle or Elcamino built at the Kansas City Leeds plant,with the 396/375HP L-78 engine & Manual trans.
Kansas City Leeds plant only made Chevelles-Elcos-Station Wagons for Chevrolet.
The fact that it's on the later issued #854 block is a mystery,and I don't believe the Corvettes used the #854 blocks either and they started with #400001 in 1968.

The '854 block was a 396 ( actually 402 ). No Corvette
ever received this block from the factory.

The 854 block was first cast around July/Aug 1969, replacing the 272 casting. I have and 854 CE block in my 69 Camaro dated H 69 (Aug 69).

Hotrodpaul you are at the place that stumped me,the EG and D 7 7 would be Chevelle correct for 67-68 but the fact that it's a 854 block cast in early 67 is what through me?I also swear the stamp is IEG and not 1EG.It does have the big cooler outlet above the filter so im sure it's a 4 bolt but even if you forget the front pad the D 7 7 casting on a 854 block seems waaayyy early!

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.
