As for the pump flow Skip himself told me the '35-36 flowed no more than stock, his later pumps had better impellers. If they are flowing more I may remove them to keep from pumping fluid out of the filler neck at speed.
By the way, at just what RPM are you getting those claimed flow rates?

I am sure Skip didn't tell you that, call him to verify that. The stock pumps and his pumps have a variable output depending on speed. At about 2,800 RPM's his 36 pumps put out 92 gallons in 5 minutes and at 1,400 exactly half at 46 gallons. G.M.
