Drivetrain questions - 64 Dart

Ok I played around with that for a while. If I step up from say, a 3.23 to a 3.55, the speed goes down, assuming all else is constant. Why would that feel better?

Also, i think I sort of understand transmissions a little now. In the high gear, it’s 1:1 from the engine, and at lower gears it’s reducing, so at the same rpm you’re getting fewer revolutions of the driveshaft. Correct?

The neck snap is from the rear and having more "leverage" to turn the wheels. less effort from the engine means more torque can be applied etc.

3.23;1 means for every 3.23 revolutions from the driveshaft, there's one revolution of the wheel. With 3.55;1, the "lever" is "longer" so less force required and so a "weaker" engine can "pull" more. Make sense? I'm not good at explaining it.

If you step down, say from 3.23 to 2.73, the "lever" is shorter and takes more power to turn. it's the difference between your 1/2 ratchet and a breaker bar. At every point along the driveline, there's reduction to some extent.
