You can hardly compare a hand built 7000 rpm performance bike with a production outboard motor on cost alone. Can't compare it to passenger cars either. Was that rating in the post war period or in the '50s ? The AC Bristol was again a performance machine but it was 10 years later which makes a world of difference. I had a 149 ci Chrysler that put out 215 hp but that was in this century, a world away from the 40's.
