OK what year car do you have? What's wrong with the VIN on the lower Left Corner of Windshield. or on tag on drivers door, or if it has not been removed on of the Option tags in the center console or rear storage compartment.

The information you mention would be applicable to a '94 Chevrolet likely maybe Camaro with an LT1. Here's a possible VIN that if your information was correct.
2G1FP22PXR2224912. Could it be a full size GM car? Yes. Is my information correct? This much of it is.
BTW - The VIN is my fabrication!!!!
1 is Chevrolet
R is model year.
The rest would be the sequence of the VIN.
Is it supposed to be a '94 LT1?
If you've a complete engine with all components then components could be used to ID. There's maybe 8 digit numbers on the fuel rails that could be used. Post a snapshot or two of the engine.

If you only have engine. which I believe WVZR1 is correct is from a 94 z28. Are you using from harness with engine or a different one? What are numbers on PCM? Corvette would be 1 R1xxxxx

I mentioned a snapshot to confirm what it is and suggested an attempt to ID components.
This VIN will pass the test for a '94 vert!! 2G1FP32P2R2224912
IF THE DERIVATIVE IS CORRECT AND IT WAS SOLD TO THE OP AS AN LT1 then one of the 2 VIN I created I believe would be correct.
If you took the last 8 to a dealer it would maybe confirm it actually isn't a correct 'derivative'.
OP ain't been back.

You're wrong. The last 8 will give you only ONE vehicle. Year, Assembly Plant, and Sequential Number. THAT plant, THAT year, ONE specific sequence number (6 digits).. How can it POSSIBLY be more than ONE vehicle? It can't. The first 8 can be the same for tens of thousands of vehicles. The GM system reconstructs the first 8 plus check digit from knowing what specific vehicle the last 8 is from.
I've bought lots and lots of parts with only the last 8. Haven't got a wrong part yet. The last eight is unique to only ONE vehicle.
Cheers.

This admittedly reconstructed VIN is not valid.
This will also come back as an "invalid VIN"
The OP's engine came out of a Firebird.
I was at my buddy's repair shop today. There was a 1995 Firebird and a 1994 Camaro parked side by side. I've deleted my posts in this thread, but I learned something and will pass it on. I participate in Forums to attempt to learn stuff.
Remember I asked "did they really produce 124,912 Camaros at St Therese in 1994?" They didn't. The OP's engine came out of the 24,912th FIREBIRD produced at St Therese in 1994.
What I learned is that what I call the "carline identifier" (first digit after assembly plant, or 12th character of the VIN) for a Camaro is "1". The carline identifier for the firebird is "2". (I was also in error that the carline identifier is always an odd digit. I was right about it usually being a "1").
The third digit in the long-VIN is the Division. On the Camaro, the Division is Chevrolet, and it is a "1". Pontiac is a "2".
So WVZR's reconstructed VINS won't work because Chevrolet 3rd = 1) doesn't build Firebirds (12th = 2 = carline identifier). Change the 3rd to a "2" and they would

Your Firebird theory won't work because if it were a Pontiac the digit preceding the R on the derivative I'm quite sure would be a 2. OP ain't been back and I'm not interested in 'debating' it but as a matter of interest I'd think you could take the last 8 to a dealer and ask it be decoded for you. I don't have an excuse to call one of my parts guys and I seldom do unless I'm interested in a buy.
I don't believe you can use the cars you mention as examples sitting 'side by side' - if either of the cars were an LT1 you could check the pad and I'd wager the 'derivative' would be 2S..... on the Firebird and 1R .... on the Camaro.
If it helps here's a '94 VIN CARD https://gsi.ext.gm.com/dealerworld/v.../vincard94.pdf
I understand nothing you mentioned about the random 12th digit. MY post #4 I believe to be accurate information.

The 1 would mean Chevrolet division. Most GM plants have sisters both f bodies com from the same plant. 2 would indicate Pontiac. 1R2 Camaro 2R2 Firebird
With the lt1. The 92-95 doesn't have a crank sensor for obd2. 96-97 has a crank sensor. The 92-93 batch fire and uses slightly smaller injectors 22 vs 24 lb. The 94 + uses sfi the smaller 22lb injectors could cause a lean condition with sfi. The obd2 engine will run on all of the the harnesses and computers. The crank sensor will be unplugged. The obd2 harness snd PCM will require the crank sensor used in the 96-97 engine.

Chevrolet engine? - I can't buy that either. GM engine found in multiple GM car-lines
That's why I posted the VIN card for you. The VIN derivative matches the 3d digit of the 17 digit VIN regardless of the components 'source'
For a St Therese F-car, you can't have a "1" in the 3rd (Chevrolet) without a "1" in the 12th (Camaro). And you can't have a "2" in the 3rd (Pontiac) without a "2" in the 12th (Firebird). The 3rd is the Division. The 12th is the carline.
Chevrolet didn't produce Firebirds, and Pontiac didn't produce Camaros. The division and carline must match.

This might answer many questions regarding VIN 'duplication' and relying upon using only the 'last 8' of a VIN when buying/ordering parts.
I tried to fabricate a Firebird VIN using the last 8 of the VIN. An LT1 wouldn't work but a S (3.4L - V6) did.
Here's the F'bird VIN 2G2FS22S1R2224912. Identical LAST 8 to my Camaro fabrication. The 1 as a 'check digit' is purely coincidence.
I also for just a thought tried CompNine using my fabrications. The 'test' used to supply only a sample but now it appears that if you enter a GM VIN newer than '90 you'll actually end up with a build date for free and if a report is available. I mention from time to time using CompNine for 'rarity' - I've not used CompNine since it moved from the FREE to a pay/subscription format. Enter an invalid VIN and it just says 'NOT AVAILABLE' (I tried the LT1 'vert for the Camaro).
Enter a VIN and if you get a positive response consider maybe the purchase if you're interested in RARITY.

IHBD- Take the last 8 as I suggested and see if your 'parts guy' can confirm for you.
Interestingly the F'bird was a Feb build and the Camaro a July build. I didn't pay for either.
