Well, there's your problem!  [ Grin ! ]

Back in my misspent youth I once created a Corvair engine that 
overcooled.  I took too many things off!  It was a stock 1965 140, fully 
deflashed, with not only the lower shrouds removed, but also the front 
shrouds (the ones to which the lower heater hoses attach) trimmed to 
just the innermost piece, and the rear ducts (the door assemblies) also 
trimmed to just the innermost part.  (These innermost pieces extend down 
to the midpoint on the cylinder barrels and heads.)

Street-driven that engine NEVER reached operating temperature.  Full 
front shrouds and rear ducts went back on it in relatively short order.
