Flathead runs idle 18-21 vacuum. 19-20 normal idle.

But with blowers and multicarbs it changes, lowers.

Beyond me, best of luck!

Not sure I know much about sbcs, but I'm not sure they run full advance at idle rpm's.

Just because a motor preforms on a stand or in the garage, Doesn't mean that it will do the same thing when you put load on it.

If you are smoking the electronics, it might not be vacuum.

Interesting to see how it goes for you.
