I have a Duraspark II distributor recurved with 10L weight on the centrifugal advance and a Crane Cams adjustable vacuum advance pot for a backup if needed, but my newly installed Crane Cams digital distributor is working just fine with 9 centrifugal and 3 vacuum advance settings tweeked from the OUTSIDE of the distributor with a tiny screw driver. How sweet it is!

ok, I called Napa and no listing for a "Ford DSII Dizzy" He said that if I get a part #, he could cross-ref it. So should I call Ford or does someone have a part #?

Application:
1978 400 stock replacement distributor.
You will need to find someone with a distributor machine to adjust it to:
=======================
Centrifugal Advance Start: 0-0.5° @ 350RPM Finish: 14° @ 2275RPM
Vacuum Advance Start: 0-1° @ 5" Finish: 12.5° @ 25"
Initial Timing: 10° BTDC, 6°BTDC California.
Vacuum given in inches of Mercury (Hg).
RPM specified as distributor RPM.
Degrees specified as distributor degrees.
---------------------------------
Double those values for crankshaft figures:
Example: 0-0.5° @ 350RPM distributor becomes 0-1° @ 700RPM on the engine.
========================
The above specs will be close for a non-EGR application.
