Oh yeah, I hope so. This one is 360 cubic inches and makes 205 horsepower at 2700 RPM. It is built from "certified" parts. It is essentially a hot rodded Lycoming IO-360. It has high performance fuel injection, it has been balanced, blue printed, the cylinders flowed and ported on the bench and has been modified for continuous inverted flight. About the only thing it has in common with your "Thing" engine is that it burns gasoline.
I kinda wish I had a Thing. Those were fun, I built a few VW engines up once, one for a Ghia convertable and another for a Blue Hippie Bus, it would pop wheelies and was fun on the beach. Those are approx 100 cubes, well, the Ghia was 1860 and the bus was a 2180 with dual carbs. J
