Reply to "Need help with ignition setup and Bad MSD 8350"

The MSD 8350 is a fine ignition. Lots of guys are running that ignition without issue.

The MSD 8477 Distributor (magnetic trigger & vacuum advance) will indeed function with the Ford Duraspark modules. You don't want to use the large diameter distributor, stay with the narrower version. There is no electronic module inside the 8477 distributor, just an advance mechanism and a magnetic trigger mechanism. Easier to calibrate than the Ford mechanism, and better working in my opinion. I'm a Ford guy, nobody questions that, I prefer Ford parts 90% of the time, but I don't like Ford distributors. And I am in no way the only person who feels that way. The performance of Ford's centrifugal advance mechanism degrades too quickly for me. And the taller narrower aftermarket distributors have fewer intake manifold interference problems.

To use the MSD distributor in conjunction with a Duraspark module you'll have to splice wires, or add connectors, or fabricate an adapter to convert from the MSD distributor connector to the Duraspark distributor connector.
