[FC] Camshafts

Probably an OT-10 would get you what you want.  It's a dual-pattern cam, 
so has more area under the curve on the exhaust profile than the intake 
profile, which is a big win for a Corvair engine.  It's also a mild 
enough grind that it won't cost you any torque in the bottom end or 
midrange.

William Wynne (who builds Corvair engines for airplane use) has tested a 
number of different cams and chose the OT-10 because it gave the most 
power below 3500 RPM.
