I agree. My fully restored 1940 Chrysler Royal Coupe has the 241.5 flathead 6, 108HP. It weighs in at over 3600lbs, and gets over 20mpg with the original overdrive transmission. Why can this old Chrysler get by with only 108HP, and my wife's 2005 PTCruiser convertible has the 180HP Turbo and only gets 21 around town and 28 on the highway!
