According to the vin I have a 1981 El Camino with a 4.4 v8 with all the ccc stuff. The engine block says it’s a ‘78 305. The computer stuff is long gone and I found the wiring stuffed into the fender. I have an intermittent miss I’m trying to fix. The distributor looks like it might be for the original ccc system. What do I have and how should I proceed? I wanted to do the usual cap, rotor, plugs and wires to start with, but now I’m not sure.
