Reply to "Duraspark distributor cap Pantera"

Hi Simon. Yes- using the small distributor cap is a good idea- indeed, it's the only cap that will fit an unaltered engine. All known big caps, stock or aftermarket WILL hit the firewall. And even if you fiddle with it and find a spot where you have maybe 1mm of clearance, the engine moves around more than that in its motor mounts under full acceleration. The cap bumps something solid and moves against the spring clips that hold it down, and the very next thing that happens is, the rotor breaks and the engine quits! I used to actually carry a spare cap & rotor in our Pantera for the occasional rescue on the road.

Its easy to shift the entire engine & ZF backwards 3/8"-1/2" for more distributor cap clearance, but many owners just are not able to do this. For them, a small cap with new wires is the practical solution. FWIW, a 1/2" move is the max I recommend because that small amount snuggles the back of the oil pan sump very close to the rear crossmember under the ZF. Trying to go further back puts you into a whole pile of other things that will now interfere. There are illustrated articles on this subject in the POCA Archives, with our car as an example from the '90s.
