Thanks! so an American beat the Aussies to it way back in the early seventies using engines from an RX2! I did a search on Andy Brizio and it said that after the twin engined Deuce he also built a 27 using a single RX2 engine.
Back then a lot of people believed that the Rotary would take over from the Piston engine and everyone was working on Rotary projects (including GM with their Rotary Corvettes).
