Inliners International Forums General Discussion Engines No VIN on my engine block

Hi mshaw230 . . .

The engine serial number and the VIN have never been synchronized by Chevy AFAIK. There are some States that have been known to use the Engine Serial number to replace a missing VIN tag to Title an old vehicle . . . leading some to believe that these numbers should match.

Engine serial numbers were created to show when and where an engine was assembled:
Old Car Manuals Project

A car with a VIN and engine SN of contemporaneous vintage are so called 'numbers matching'. For example, a car that shipped in April of '50 with an engine assembled in February of '50 would be considered likely original and numbers matching. But a restorer could use a block from Jan to Apr of '50 and still have a numbers matching car. An engine serial from a later date being an obvious transplant . . .
