I have a 71 1110 pickup with a 392 in it. Attached are a couple pictures of the distributor and a Mark 10 capacitive discharge ignition. Can anyone tell by the picture what brand distributor I have? I am not familiar with the Mark 10 but by the looks of the wiring job I can only assume it is aftermarket. I am having ignition issues and am wondering if I can disconnect the Mark 10 and replace points, condenser, cap, rotor, and start over. From my limited knowledge and research I think the Mark 10 is a performance add on that is not really necessary with a properly tuned and setup distributor. Thanks for the help! I'm located in Troy Ohio FYI and am slowly becoming addicted to IH vehicles.
