NO. It needs ported vacuum. This means that it should only have vacuum on it when you bring the rpms up off of adle.
All engines must have a harmonic balancer instaled on them. Balanced or not. Hook a vacuum gauge to direct vacuum port on intake. That is a place that will have vacuum on it when the engine is running at an idle. Then read gauge and move the distributor until you get the highest vacuum reading. It should be 18 to 21 inches of vacuum at an idle.
With the engine warmed up and at idle, disconnect the vacuum line to the vacuum advance.Hook up your timing light to number one cylinder. Slightly loosen the distributor. The timing should be about 4 degrees. Move the distributor until the pointer is at 4 degrees. Tighten the distributor and reinstall the vacuum hose.
18 to 21 inches at idle
Is the vacume for the distributor TIMED vaume or full vaume at idle???
19 to 21 inches at an idle.
That engine should have 18 to 21 inches of vacuum at an IDLE. You can find a vacuum source on the intake manifold.
You need a vacuum gage, hook it to a vacuum port that has constant vacuum. It should have about 19 to 25 inches of vacuum at idle for a stock engine if the timing is set correctly. Now quickly snap the throttle wide open the gage should drop to about 5 then back to where it was. You can also set the timing by adjusting the distributor so you get highest vacuum reading.
Connect the line to a source that is above the throttle body on the carb. It should be a source that has no vacuum at idle.
Look on the carb for a small vacuum source above the throttle body. You would want one that has no vacuum at idle.
