I think you've been overly optomistic with the speed figure for a Cherokee Six
with the 300 hp engine. I used to figure about 145-150 knots with a full load,
which is the only way I ever flew one. Your fuel figures are about right. The
sweet spot for the Six was between 6,000 - 8,000 feet.

When I was regularly flying a 300 it was usually me two pax. No extra
load. Probably about 650lbs total. AS was almost always just above 165.
