Gears, gears, gears. Change the rear end gears to 3.45 or 3.73. After that, install a free flowing 2 1/4" exhaust system. The 2.3 exhaust manifold is pretty good as is. Do all the free mods; chuck the air intake silencer, advance the timing as far as you can without pinging, and get rid of as much unnecessary weight as possible. Also switch to synthetic oil. I've done it on three cars, and noticed a slight increase in power.
