Listen to this guy ^
There is only one way to make power, and that is to combine more cylinder pressure (not compression ratio, don't get these terms confused), with more/better exhaust scavenging, and to multiply these factors by adding either cubic inch displacement, adding raw oxygen (nitrous) or positive displacement (forced induction).
If your 302 is strong in all 8 holes, and doesn't make any blowby or leakdown, then at 5000 foot elevation, the best way to add cylinder pressure (without replacing the engine) is going to be with either turbocharging, supercharging, or nitrous. A direct drive centrifigal blower is the best mechanical method (meaning most efficient for the $) for acheiveing this goal on a small cubic inch engine, IMHO
I also like jhv48's point about the gears- lower rear gear can mean faster RPM ramp rate- very beneficial at higher altitudes.
