AI caption July 2017 · Photo 132 of 189

This is a photograph (not a paper document) showing a stamped metal engine identification tag attached to a bare cast-iron engine block sitting in a cardboard shipping box with plastic wrapping. The small aluminum-colored tag is stamped with two lines of text: 'C9ZE 6009 C' on the top line and '428 CJ' on the bottom line. The '6009' is the Ford basic part number group used for engine assemblies/blocks, and '428 CJ' identifies the engine as a 428 Cobra Jet. The prefix 'C9ZE' is a Ford engineering/part code. The photo shows part of the block's front face with a dowel/oil gallery hole, threaded bolt holes, traces of red-orange paint on the casting, and what appears to be the crankshaft and harmonic balancer area visible to the right. A reader can learn the specific Ford part/engineering number stamped on this engine tag and that the engine is identified as a 428 Cobra Jet (428 CJ). No fuse data, wiring information, torque specs, or additional text is present — the only textual content is the two-line stamping on the tag.
