In todays modern collector car world, cars are being sold as numbers matching when the original engine has been replaced with a correct part numbered, date correct block. Sometimes this even means the serial (VIN) number has been re-stamped to match...
When shopping for a classic be sure to ask if the drive train is original to the car. You will be surprised by the answers the seller comes up with to justify his car being matching numbers.

When a cars Vehicle identification number (VIN) matches the number on major components like the engine. This essentially means that major components, like the engine and transmission are original. US Auto manufactures been matching numbers on major components in 1960 (Most Chrysler's and the Chevrolet Corvette) and other General Motors and Ford cars in the mid to late 1960s.
