the sprint car engine known as the McMahon Air Cooled, in Speedy Bills museum

  1. Wow, it was built in the 40's when a crate was something a hot rodder sat on. This is sheer genius-how do you come up with such a combination; Ford V8-60 crankshaft and rods held in a sheet steel block with four Triumph/BSA cylinders and heads on top. Because these are hemi heads this uses three chain driving camshafts, (the chains also drive the oil pump and mag). The standard V8 60 cam runs the intakes, and the other two operate the exhaust. The guys posting on this thought the intake was a heavily cut down Offenhauser unit. Cool the way the headers are grouped like a small block Chevy-which was about 5 or 6 years after this.

  2. This reminds me of the prototype V8 engine that Ducati created for F1. Basically 4 V-twins bolted together. http://www.motorsportretro.com/2014/12/ducati-v8-f1-engine/
