I am done with Pertronix. Going to use a dual points distributor now and picked up this Motorcraft dual points distributor today in what appears to be excellent shape. Looks like the code on it says 3D8 in addition to the C5OF12127 which I am told is an early 70s replacement for the HiPo. Only wondering if I should swap out the gear on it given my current engine in the Hertz is a mid to late 80s 302 with a roller cam in it. But it also has roller rockers. Not sure if a roller cam and roller rockers can coexist but definitely has the roller rockers. The gear on a distributor has to match the gear on the camshaft from what I have researched and recently learned. The distributors from that era were mostly cast iron gears and the gear on an 80s Mustang 302 is steel? Therefore change out to a melonized gear?
