Many know Trenton Engine as the place where V6 engines have been made for decades, but the first engines made there were V8s, built from 1952 to 1978. In early 1952, plans were to only make truck and industrial engines including the blocks and heads; but the immense popularity of V8 engines brought an expansion of both the plant and the plans. Trenton ended up making the original “double rocker” engines, now called first-generation Hemis, for both cars as well as trucks; then came the “poly” designs, and then the B and RB engines moved in (one line for each, at first), and then the 426 Hemi. Most of these photos are from 1962.
But first, here’s the cafeteria.
And a Hemi engine from 1966.
The photo below shows the final inspection line of Department 72 Main; they made the B engines (350, 361, 383, and 400). After the inspection, the blocks were put onto the final assembly line. You can see letters spray painted onto the blocks (look just below the girder of the line), C, B, etc, which represent slightly different widths of the bored cylinders; these were matched to pistons, which were likewise made and then measured and sorted into size classes. These measures were needed to deal with manufacturing variations, which finally disappeared for good during much later V6 production.
