engine rebuilder in NJ?

I'm looking to find a company in pennsauken NJ. The motor in my car has a tag glued to the block (/6) that says--> remanufactured engines and parts pennsauken NJ and has some sort of serial number.

I'm trying to find this company to discover when the engine was rebuilt. has anyone heard of this place? may be out of business since the car moved to FL in '89 or '90
