You want to shift gears as the engine is falling off the back side of the power curve, so as you up shift and step on the gas, you'll be making enough torque to push the car along. Continuing to run the rpm's up after the cam stops making power is often pointless.

You'll have to look at the cam specs and see what kind of power band you have.

The bottom end! If the top end is all built out to run to 7,000, but the crank and rods are all original cast iron pieces, you might want to re-think how high you want to run it.
