To set the dwell on a 326 Pontiac, you'll need a dwell meter. First, connect the dwell meter leads to the appropriate terminals on the ignition coil or distributor. Start the engine and let it warm up to operating temperature, then rev the engine slightly to stabilize it. Adjust the distributor's points gap until the dwell reading is within the specifications, typically around 30-34 degrees for a Pontiac V8.
It is located on the harmonic balancer.
