Rebuilding a 70's-80's electronic dist. for my 318. I've got two factory Chrysler shop manuals. One is a '74 and the other is '83. Both have specs for the resistance across the pick-up coil. The old one sais 350-550 ohms is acceptable and the newer one sais 150-900 ohms is ok. I dug out 8 old ones kicking around and got these results...257, 265, 268, 270, 275, 278, 283,and 290 ohms. These coils came out of working units so I know they were at least usable. They fall within the newer spec., but what's better? More resistance or less?
