There was a 16V92. It was made by attaching two 8Vs crankshaft to crankshaft.
Love those old Detroit & the larger GM-Cleveland/Electromotive two-strokes. I worked on them for most of my Navy career and for a period of a few years that I worked at a Army depot on Armored Personnel Carriers. From the 3-53 up to the 16-278s. That 6V-53TI is probably what's being used the APCs now.
