this brings up a question if anyone is aware of a database of the VINs matched to the engine serial numbers... I have been on a lookout for such a database for several years now, to no avail.... good thing we can do the real OEM and the check the built sheets based on the VINs...

With the engine serial numbers, one could theoretically "verify" if the engine in his prospect buy is original, or may have been swapped, and if it were swapped, to trace to original car to see the fate of the donor...

i know, i know, sounds like too much of investigative work, but aren't a PPI or a carfax investigative tools to begin with?...
