Either that, or put a ruthlessly efficient and powerful fan on these engines. Cooling on Corvair engines is air flow limited long before the fins become the limiter.

"Pump more air in".  But for Corvairs, this means cooling air as they are 
cooling limited FIRST!  To improve cooling, the cylinders and heads need to 
be more expensively redone with finning more like an aircraft engine.  As 
they are, they are economically cooled and run just fine that way but will 
never deliver300 hp in a 24 hour roadrace.
