Merc 20H conversion year?

[Tim Chance]

Also remember that Champion had the about 15 cuber "A" engine designed by this time.
They had built 3 engines at the factory. Chances are this engine would easily run with a KG4
racer. What do think Carl would have done if they built these and they were approved???

In the late 50's or early 60's I drove an alcohol burning A Hot Rod in A runabout once at a race in Minnesota. I think it belonged to Larry Rogers, a Champion engineer. It was competitive with an alky Quincy/Merc, but not with an Anzani or Konig. This might have been one of those three engines.
