You can’t see much of it under the “doghouse,” but here’s a 226ci “Super Hurricane” flathead six. It was rated for 105hp stock. The standard compression ratio was 6.86:1, but many Colorado trucks were fitted with the optional high-compression, 7.3:1 ratio head. At the time, it was the most powerful engine in the Jeep lineup.
