No
electronic ignition on the 93, no controll. just set your timing.
A dwell meter is used to check the setting on a POINTS type ignition system, these have not been used in quite a few years, and for sure not as late as 1993.
timing: 5 degrees btdc. electronic ignition sets dwell automatically. timing: 5 degrees btdc. electronic ignition sets dwell automatically.
go with 27 on the dwell and 4 btdc on timing
Dwell angle is simply the amount of time the points or electronic ignition components are in a closed state to charge the primary side of the ignition coil for firing of the spark plug.. This time is expressed in distibutor rotation, hence the degrees..
to my knowledge 1980 Chevy v8 engines didn't have ignition points, and dwell settings are for points.
Cam dwell is: The number The number of degrees a cam rotates during the time the object controlled the cam does not move. The breaker points in the ignition system of a reciprocating engine are opened by a cam. The cam dwell, or cam dwell angle, is the number of degrees the cam rotates between the time the breaker points close and the time they open.of degrees a cam rotates during the time the object controlled by the cam does not move.

Dwell is 28-32 degrees and the plug gap is .035
Ignition system is controlled by Vehicle Control Module (VCM). The VCM monitors the information from various engine sensors, computes the desired spark timing and controls the dwell and firing of the ignition coil via an (IC) line to the ignition control module. Hope this helps.
I believe it has electronic ignition , so there are no points
