Hi guys, Questions on the ignition portion of the 6 to 12v conversion. 1949 GMC FC102 228 engine.
Original 6v distributor is Delco-Remy 1112356.
1. Are the points and condenser 12v specific in the conversion? Mixed details in my research and many suppliers offer complete conversion kit, but I see a lot of “Pertronix” electronic and it sounds like keeping points and condenser are preferred over that. I actually prefer points and condenser.
2. Any good recommendations for quality points and condenser? Is anything American made?
My original 6v coil is a Delco-Remy 1115328.
1. I was able to cross reference a Rock Auto 12v coil in a conversion kit but could only find 12v applications on 1950 GMC 228n(see pic). Do I need a resistor? Offers with or without.
My '52 GMC 228 came to me 12 years ago already converted to a 12v negative ground system. The coil was marked "12v" and had an internal "ballast" resistor that could not be bypassed like a slightly more modern (say 1956 and newer) system with an ignition switch with a start position (or a stomp starter switch with a bypass terminal), 12 volt coil, points and condenser can be when starting. I think the C15 or UC15 in your post would be such a coil. Some (me included) would argue that using such a coil would cause starting to be harder because the lack of an external bypass for the ballast resistor and the coil having a non-bypassable ballast resistor. Mine seemed to do okay.
That said, I've been using a Deve designed HEI system for years now with no complaints and very quick starting under both hot and cold conditions.
As for a condenser, contact forum member Jon G.

Read this and contact Jon G to get one of his condensers. After experiencing brand new condensers fail almost immediately upon installation, I installed his units in every vehicle I own that uses breaker point ignition.
I have never converted any vehicle from points to Pertronix. My '56 Coupe de Ville has been my primary vehicle for 23 years and points work perfectly.
