How do you set dwell angle on the Points in a 390 FE Engine?

I quote myself from another thread.


One trick you might try is with a helper.
Have the helper crank the engine while you are adjusting the points. WATCH OUT FOR THE FAN! Use 2 screwdrivers. One for adjusting and the 2nd to tighten the point's screws once you got them adjusted and are holding them there. As the engine is spinning over the dwell meter's needle will bounce back and forth about 15 degrees or so. The middle of the bounce sweep is where the points are adjusted at that moment. So as the helper is spinning the engine over adjust the points so 30 is in the middle of the bounce. Hold the points there, tighten both of the screws, then check the dwell with the engine idling. Also double check the timing after you get the points adjusted. Adjusting the points changes the timing.

Now that I checked the Dwell it was about 15 degrees all in. Reset the Dwell now at 34 and after reseting the timing this thing runs great!!! Thanks for the help... Found out why the Steering was all over the place. The Drag Link is broken on one end. No more driving until I get that replaced... Just glad I didn't end up in the woods if that would have broke...

I love my Fords, but Chevy had a great idea when they put the little sliding door on their points distributors so you could raise it up and adjust the dwell with the engine running with a small allen wrench.

Great ideas ford by moving the dizzy to up font on the engine to make dizzy work much easer.

So GM put the little slide door in the dizzy cap:

Which both ford & GM had good ideas:
