Swapped to Muscle - 75 Duster Daily build
Since getting it in the driveway, the first update that I wanted to do is get the ignition updated. I researched into like Pertronix ignition systems, MSD, etc. But when searching on here, I found out about the HEI conversion using a GM 4-pin ignition module. So after about a week of research, part number gathering and what not, I got the components and wiring to get that done.
So I went with a cheapo GM ignition module from Autozone and MSD 8202 coil just to see if that would do the trick. Got the jumpers connected for the ballast resistor bypass. Hooked up the coil with a new positive wired to the ignition module along with the ground. The current distributor literally had 3 different places that it was spliced together so I replaced most of that with new wire and new connector. Got that new connection from the distributor and ran new wire to the ignition module. I reused the wire to the coil to the ballast resistor as the ignition on wire. At the same time, I figured that with the hotter spark, I may as well get new wires, cap, rotor and plugs. Got those in with the larger gap (I set them to .45) and tested. I was shocked. It started right up and the miss that was there was almost gone. Runs way smoother now.
Since that test was successful, I made up a bracket and reused some old heatsinks from a PC that I had laying around and mounted to the location of the old ECU and ballast resistor. I will update the connections with better connectors here soon as this was mostly for testing to see if it would work.
