Edelbrock: vacuum ports
The correct adjustment of a vacuum advance unit is critical to ensure that an automobile engine runs at its peak performance. The vacuum advance mechanism allows the distributor to vary the spark timing to compensate for the load and speed requirements of the engine. During light loads on the engine, the cylinders burn leaner and require the spark to be initiated earlier in order to obtain optimum power. The vacuum advance unit provides this varying spark advance and improves the fuel economy and throttle response throughout the operating range of the engine. Set the mechanical timing of the engine.
Distributor to Carb - Which Port? Edelbrock
Is this a better way to go with a street engine? What kind of timing should I be running and should I disconnect the vacuum advance? First, on a street-driven engine there is no good reason to lock out your ignition timing. If we had to use a generic maximum advance that seems to work for most pump gas engines, somewhere around 34 to 36 degrees before top dead center BTDC is a good number. But with this much initial timing in the engine it will be difficult for the starter motor to crank the engine.
