What is 454 ignition timing?

Answer

It is possible to set an engine's timing on a 454 by using the manifold vacuum on the vacuum advance. First, set the initial timing to 15 degrees and the total to 35 without vacuum advance. Then, connect the vacuum advance to the manifold vacuum and set the vacuum advance. Give it an additional 15 to 20 degrees advance in an idle vacuum state. Then, set the idle speed and adjust the idle mixture for the best idle.
