the 180* thermostat and colder plugs will allow you to advance the timing more without pinging which = MORE power. Willow, you have a distributor on you car so you wouldn't need a chip, you can advance your timing by adjusting your distributor if you have a timing light.
ALSO the 32C plugs you can get at a local ford dealer. 32C are the last 3 numbers but they SHOULD know what you are talking about.
