Absolutely right. I've written time and time again that my TKO's first four gears will take me to (with a solid lifter cam, mind you) over 130MPH. My .64 fifth gear is used for one purpose, and one purpose only. And that is calm, relaxed, easy highway cruising, generally in the low seventies. There's a sweet spot where the engine is actually relatively quiet and you can chat with your passenger, or just hear yourself think. It is one of my absolute favorite things to do with the car. I'd still point you at the 3.54 though.
