Everyone know how Chrysler stamped the motors in late 60's and early 70's ( could be longer/earlier, not sure) ?.............." Numbers Matching" or " Not Numbers Matching "..................Do they still stamp the motors of newer cars......like the 2006 Charger?..........Why did they stamp it in the first place?........Why was the original motor important back then?..........Warranty issues ?

You've seen the original Gone in 60, right? From what I understand, the main reason they stamped VIN #'s on engines, trannies, trunk lips, radiator shouds, etc. was because of guys in chop shops.

Well, and for restorers down the road.


I'm not sure about every make, but my daughter's 91 Mustang 4-banger has VIN #'s easily visible on stickers (that's dumb) on both front fenders & the hood. So I'm assuming they're still doing it.

Vin's were stamped on the engines, trans, and body, for the same reason that there is date coding on parts. For quality control issues. If someone had a problem with an engine, that was fine. But if there happened to be 500 motors that went bad, and all were cast around the same date, by having them date coded, and the vin's on the engines they would be able to identify which ones were going to have problems and do a recall. Much like todays companies.
