351FUN Posted June 4, 2023 Share Posted June 4, 2023 I'm about to remove the duraspark box and all of these unused plugs, but mostly out of curiosity what did they go to originally? It's been years since the engine swap and I can't remember. For context none of the factory ignition wiring is still in use past the key switch turning the starter motor. HEI distributor is direct to battery and if it weren't for the steering wheel lock I probably wouldn't still use the key switch at all. Link to comment Share on other sites More sharing options...
