The "Flying Millyard" 5 Litre V Twin first test run

This is the first test run of my 5 litre V Twin engine based on two Pratt & Whitney R1340 aircraft cylinders, all other parts are hand made including the crankshaft, con rods and crankcase wooden moulds, the crankcases were then cast in aluminium. The engine runs a dry sump with twin pumps, twin SU carbs, points ignition with manual advance / retard and twin plugs per head.
