Reply to "Duraspark vs MSD distributor"

panteradougMember

At the risk of offending the Pantera ignition Gods: Something that wasn't mention but is relevant to this discussion.

The Ford Duraspark distributors were designed to run with the large diameter cap. Sometimes people choose to go with the MSD just for the reason of the smaller cap.

You can run the Duraspark with the smaller standard cap (and rotor) for better clearances in the Pantera. I do and regularly run the car at high rpm and have not had noticeable issue with cross fire within it.

With Weber 48 ida carbs there is no choice. Only the small cap will fit.

The risk of fire from arching with the small cap is over rated. The fires are not caused by electrical arcs. They are caused by reversion into the carbs... and they are only small fires.
