Hello guys,
Is there someone who can tell me the right timing advance for a chevy 454 mark 4 1980, with the engine warms up, choke open, vacuum advance disconnected and plugged at idle.
I read so much about it and never the same. I have an Edelbrock performer 1413 800cfm for carb and an Edelbrock 2161K Performer 2-O Intake Manifold.
What's the ideal idle to adjust timing, and after adusting if i put it at 600 rpm is it ok?
Sorry for my poor english, I look forward to your answers, thanx.
Michael.
