440 Engine tuning suggestions

I believe Deey is meaning 30* including vacuum advance . But I would still be hesitant to do that. Besides unless the OP know how to curve a distributor he will have way to much total when done .

Check again.He said 30 at idle. It doesn’t need it. The only way to do it is hook up the vacuum advance to manifold vacuum.

It’s poor engine building that requires that kind of idle timing.

Fortunately for the OP his engine was built better than that.
