In the spirit of other cars we have or have had. I was thinking of a VW Beetle I had that we installed a Corvair flat 6 air cooled engine into. The engine was built to run in reverse of it's normal direction to work with the VW transaxle. We had other conversions like this that we flipped the ring and pinion in the transaxle instead. I remember the stock VW gearing wasn't the best match for the Corvair engine. This engine shown in the VW pictured put out about 160 HP and 140 ft/lbs of torque. The reverse rotating engine caused oil to be thrown out the crank case vent tube. This was something of a problem if I remember correctly.
