Hello Guys,

Question for you all. I have a 1967 Oldsmobile Cutlass Supreme Convertible. Its super sharp and purchased it about three years ago, at the ripe age of 28. I did a lot to it. Put duels on, disc brakes, new convertible top and motor, some cragers, custom made a stereo consol, etc etc.

I now want a 1972 Corvette Stingray and trying to sell the Olds.

I want to know if I have a matching numbers car. I heard that pre 68, its tough to find if the engine is the original. I took all the numbers I could from the engine but can't find any information.

I was wondering if anyone could give me some info.

The VIN is 338677M318898

On the front of the engine it has the numbers: 557265 and says 4B

On both sides of the engine it has 554717. Below the right side of that same number is, I believe is correct, says GM380001LH

On the back of the engine it says Firing Order 18436572

Any ideas????

Also, how much should I sell it for? I bought it for 12k three years ago. Its in awesome shape. Also, I'm in Nashville, TN. If anyone has a 72 or older Stingray that are looking to get rid of, I would be interested.

First of all, Oldsmobile didn't start stamping the VIN derivative on the block and trans until the 1968 model year, so it's kind of difficult for numbers to "match" on cars older than that. If you have the Protect-O-Plate, it will cross reference the engine and trans unit numbers to the VIN, but all that proves is that one head is original.

This is a moot point in your case, because the casting number on the block that you provided is for a 1977-79 403 motor, so it is very non-matching.
