Super Six twin cam Indy engines

Not quite but its a good headline. In Griffith Borgeson's 1981 book The Classic Twin Cam Engine, there are a couple of pages on the Richards Indy engines of the late teens early twenties. The starting point for the engine was the Super Six's counterbalanced crankshaft, which was placed in an alloy one piece crankcase/block and topped with cast iron twin cam heads. 140HP at 4500RPM, very high revs in those days.

Well, that's a switch from today: alloy block and cast iron heads....Sounds very exotic.
