My question though is about the speed to horse-power. I thought that a set up like this would be super fast, "at least like a really good Yamato 302" at 65mph or so. What I mean is that an old Mark 20H or Evinrude-15/A will run in the low to mid 50s easy. Is it because the little stock 15-20 cubic inch motors are actually making in excess of 30 actual horsepower? This is an honest question. I never seen any actual horse-power ratings on many of these little racing engines except for the Yamato 80. I happen to own a Y-80, a 1956 Champion Hotrod-20, and a super-10 mercury. Thanks.
