Too much timing?
So how much is too much on these big engines? Reason I ask is I had mine set at 8 degrees advanced and the motor was good there, but for some reason I am not getting any Vacuum advance. I can tell this by using a timing light and disconnecting and reconnecting the vacuum hose and it makes absolutely no difference at idle. My 292 I6 would sound completely different when I did that. So my engine has been relying on mechanical advance...which seems to be fine as it's very responsive and pulls nicely.
Today I bumped my timing up to 12 degrees advanced and the motor sounds even better...more responsive all around and seems to idle smoother. I haven't driven it yet, but was wondering...you guys think 12 is to much? I know the factory setting is 6 degrees, but I'm getting no vacuum advance at idle. Carb is a 600 cfm edelbrock and works fine. Engine vacuum is 18 what ya call its. lol
