no.
The meter needs a dwell setting or scale. Otherwise it won't measure it with meaningful readings.
28 to 32 for the dwell and for the timing, TDC if it is standard transmission, 4 degrees BTDC if it is automatic transmission.
Dwell angle in a distributor refers to the period during which the ignition points are closed, allowing current to build up in the ignition coil before it is discharged to the spark plug. It is measured in degrees of rotation of the distributor shaft and affects the timing and intensity of the spark. A proper dwell angle ensures optimal engine performance, as too low a dwell can result in weak sparks, while too high can lead to excessive wear on the points. Adjusting the dwell angle is crucial for efficient engine operation and ignition timing.
your dwell angle will be 29 timing ( initial ) will be 6 degrees below TDC
30 degrees Dwell angle varies from vehicle to vehicle. The dwell angle is the amount of degrees the points are closed
Dwell control is typically defined by the engine's ignition system. The dwell angle is the duration in crankshaft degrees during which the ignition points are closed. This setting affects the timing of the spark, influencing engine performance and efficiency.

A dwell meter measures the duration that the ignition points in a gasoline engine remain closed during each cycle, which is crucial for proper timing and efficiency. It connects to the ignition system and displays the dwell angle, typically expressed in degrees. As the engine runs, the meter indicates how long the points are closed, helping to diagnose issues with ignition timing and ensure optimal engine performance. Adjustments can be made based on the reading to achieve the correct dwell angle specified by the manufacturer.
Point-equipped V-8s are generally accepted to have a dwell angle between 28-32 degrees. This is best set with a dwell meter. You can use a matchbook cover in a pinch until a dwell meter is used. Turn the points adjustment screw until you feel some drag when pulling the matchbook cover out of the gap. An old-timer told me this trick and the dwell turned out at 30 degrees. It's best to set the dwell at the lowest value because timing advances as engine speed increases. Setting the dwell too high will advance the timing too far at high speed and cause power loss.Remember to re-time the engine and set the idle speed after setting the dwell. Turning the distributor doesn't affect the dwell, the dwell affects the timing.My research indicates that the dwell should be checked every 3000 miles, sometimes more. I've seen claims as high as 10,000 miles. You'll have to monitor it yourself and choose the interval that's best.Good luck.
Point gap---.017 Plug gap----.034 Dwell Angle-26-31 Timing------10-12 BTDC
go with 27 on the dwell and 4 btdc on timing
12-16 thou gap and 34-36degree dwell angle for HR.
