when a car is new it came with a protecto plate (POP) used when maintenance was done at dealer. there is an engine # on it that will match one head only, so you need the original POP or maintenance records with an imprint of it.

Most people dont believe you need to have the POP and will claim they have a numbers match car if it's period correct. Some thnik it means the Julian Date on the Block and the build date of the car are date coded in a logical sequence, some think everything must be built in sequence that has a code and some are any variation in between. My personal view (only) is that a numbers match car is a car whereby every date code Olds put on a car is in the proper date sequence (example - Block Julian Date, spark plug wires, Tranny date Stamp, rear housing date stamp, etc), all of the components carry the appropriate number (water pump, gas pump, distributor, heads, etc) and all components are stock (valve covers, air cleaner, etc). However, many will disagree and challenge this. I asked this question years ago and got many answers, interested in others views as well  |

Regarding 1965 442's only, I try to look at it from a more simplistic approach. To me numbers match means the car's engine, transmission, and rear end or those major mechanical items the car was originally produced with are still installed in the car (or on hand)/along with the paint and interior matching the original data plate. Validation with a POP is preferred, but not mandatory. I don't consider parts changed as routine upkeep and maintenance as a requirement for the term numbers matching. My criteria changes on cars that are highend, unique, low production number cars...and this is only from a value standpoint. On cars that have the VIN stamped in the block, this is a requirement in my eyes.
