The Hess Hornet is an air compressor configured from a 134 Willys engine.
2 cylinders run and 2cylinders pump.
Different head and valving on middle 2 cylinders.
Has anyone converted one if these units back to an operating 4 cylinder engine?
I'm working in that direction now. Looks like other than the head it will need valves lifters and components
Also valve seats will need to be remachined into the block and likely valve guides. Don't know if it will need a different camshaft or not. Again this is something I would like to hear from anyone who have done this.
