I may have provided some bad info in the past.  I stated that the fuel vol in my wing tanks was 37 gal per side; attributing the extra to the complete absence of speed brake provisions.  However, I just got around to exhausting a fuel tank in flight, and refilled it with 34 gallons.  Of the many possible variables, the one that seems most dubious is the accuracy of the 1/2 gallon measuring cup that was the basis for the original calibration.  I"m still sorting through this one.
