And it might not ever be. But I will tell you that taking the time (years, maybe) to get your engine in absolutely perfect tune will not only benefit you on the high end of your revs it will also make your car run better at the low end as well. When I took the trouble to optimize my air flow down through the carb (the pretty S&H Chrome filter is a real choker), and concentrated on A/F tuning, the low end of my engine's comfort zone moved from low 2000's to the mid to high teens. Now, all that means is that my car does not buck and strain down at 1800 when I'm out on the interstate cruising or slowing down or gently speeding up. If I want to speed up in any fashion other than lightly and gently I down shift straight to 3rd or at least to 4th. But, before you even think of changing out any gear ratios, take a year or two to concentrate on getting your engine to run at its very, very best And one nice thing about having a .64 5th gear is that all the online speed calculators tell me my car will go over 230MPH.
