Displacement alone won't be so much of a deal breaker, what really defines if an engine is effective or not for a purpose is the power/torque curve. Maybe a 250cc motorcycle could even be a reasonable option if you were looking into an extreme downsizing which could still provide an acceptable overall performance.

Doing some math, many of those stationary engines within this displacement range would underperform some 125 to 150cc motorcycle engines coupled to a reduction gear in order to match the RPM input to a transmission. Well, what about experiencing a turbo into the 420cc engine?
