V8 Ignition Timing: Notes
NOTE:
Procedures for timing adjustment are for engines equipped with HEI-EST distributors only. Other engines are equipped with C3I, DIS or IDI ignition system. Timing on these systems is not adjustable.
NOTE:
Some engines are equipped with a socket for a magnetic probe timing meter, located 9.5 degrees ATDC. DO NOT
use this location for setting timing using a conventional timing light.
