Help identifying this Cat.

I have purchased a 1990 Pete with a mechanical Cat 3406?. The original serial number on block has been ground off and restamped with new one on drivers side and its ( 7X007941 ). Your help is highly appreciated. Thanks to all

It should actually be 7xc, that is the prefix for a reman engine from cat, without the original reference serial number or arrangement it won't be easy to identify.

You can call a dealer and get the original engine number for what was installed from the factory, that may get you close.
