GM has some larger factory made engines, including the 16V92 that I worked on a few times (part of a 750 KW generator). They claim it is a 24V71, but that really does not make sence. GM went to larger displacement if they needed it, not 24 cylinders. They did make a 12V71, but the 12V92 was more popular and larger displacement. Even the 8V92 was more powerful than the 12V71.

If you owned a boat and needed more than 1,600 HP, then the 12V149 was selected, or the 16V149 at well over 2,200 HP. I was in a boat powered by a pair of 2,200 HP 12V149's.

There was a even larger displacement, I think in the 256 or 249 cubic inch per cylinder configuration. The 645 was a engine made for trains. They where first designed by the Winton Motor Company, as train engines, then later changed to trucks and other uses, such as generators.

I know a person who owns a 253 generator (2 cylinder and 53 cubic inches per cylinder) and knew a fireman who bought a pick up truck with a 4V53 engine in it. That would be 4 cylinders.

A 53 series Detroit Diesel in a V4 configuration? I would like to see pictures of that! I worked on 2/53s, inline 4/53s, and a few 6V53s, but never saw a 4V53.
