Julian Edgar: The Chrysler A57 Multi-Bank Engine (The starting point was the L-head, 4.12-litre in-line six. A slightly revised cylinder head reduced the compression ratio to 6.2:1 from the standard engine’s 6.8:1, but production Dodge carburettors were retained. The five engines were arranged around a cast iron crankcase, with each ‘sub engine’ being geared to a common ring gear. A single central shaft handled all the output.) AutoSpeed. 6.3.2012.
