gears. depending on the ratio you have in the car now, swapping out a reasonable rear end ratio versus a sedan ratio would give an impression of way more hp than you would get out of bolt on engine mods

Best answer. Gears. No matter what else you do to the car, you'll need gears and rear suspension. Research mini-tubs so you can determine how much tire you can fit into the car, then snag a 9" Ford diff and set it up to bolt into the Chevy. Install an aftermarket limited-slip unit such as Detroit Locker, Auburn or whatever along with some good axles.

Nothing wrong with a good set of leafs, tires and Caltrak bars down to 10 flat.

This is where most newbies make their biggest mistake, starting at the wrong end of the car. First thing they want to do is drop in a huge cam that doesn't match the static compression ratio, converter or rear gear. The car turns into a turd and they're on here crying the blues and asking for help. Leave the motor alone and work on setting up the rear of the car, then install a converter based on the cam you will use, then start on the motor.
