Default VIN Number From Engine Or Computer?

I purchased a 99 LS1 Corvette engine off of eBay. Once the seller received his money he has been less than responsive with my follow-up questions about the car it came out of, internal engine mods, etc. Anyway the engine arrived the other day. I plan on dropping it into my 78 project car.

Is there a way to determine the vehicle VIN number from any numbers on the block...I haven't looked closely, but I know there must be some kind of number(s). If the engine number is associated with the VIN, how or where can I get the conversion/association to determine the VIN. Or is the VIN number stored in the PCM?

Thanks,
Clint aka billybaloneey

I've never looked at my LS1 in the '99 but on my '07, The VIN# is inscribed directly above the oil filter on the block itself.

Yes, the VIN should be stored in the PCM ... most code scanners read it, and some even use it to control how many vehicles the scanner can be used on.

Yes, the engine should have a label or stampings on it with the "VIN derivative"and Engine ID number. The label(s)/stampings will be at the back of the engine, on the drivers side, on the vertical side of the block and just above that where the head meets the block.

The VIN derivative is simply there so you can "match" the engine to the car .... in other words was this the engine that shipped from the factory .... the VIN derivative for a 1999 will look like 1X5xxxxxx ...

1 = Chevrolet
X = 1999
5 = Bowling Green
xxxxxx = Plant Sequence Number

So you compare the xxxxxx to the last six digits of the vehicle VIN plate to ensure that they "match" .... and a match means the engine came from the factory in this car.

Easiest to see if a scanner will display it from the PCM.
