Hi I have built a few four stroke engines my last being a Edwards 5 radial. I now want to build a water cooled V8 engine. I have found drawings for two, one is called the Challenger, the other is the Scorpion. The Challenger is a V8 with the one cam shaft between the cylinders, with oil pump and water pump and spark ignition. The Scorpion is a twin overhead cam but glow ignition, and using glow fuel which has oil in it, allowing blow by to lubricate the bottom end and cams.
Has anyone built ether or has experience of them or knows of any other V8’s with drawings that I could consider.
Regards Bob
