It really is a neat engine, with double overhead cams and 4 valves per
cylinder, very efficient. But it's only about 240 cubic inches; I doubt it
would do well at all in a motorhome application because of the
weight...Possibly, with proper gearing. It makes on the order of 300
horsepower, but torque won't be much because of the small size.
