Re: 1972 C20 build and adventure thread

During the tuning process, we realized that I was having a lot of issues with the truck breaking up and back firing at part throttle around town. The initial suspicion was that my cobbled together ignition system was the cause. The coils and harness were all used ebay purchases from when I initially built the truck.

In order to completely eliminate the ignition system as the cause, and to make it more serviceable, I replaced the valve covers with the Holley units that mount the coils right on the motor, then used factory plugs, wires, and heat shields along with the Holley coil harness.

Its not particularly pretty, but again, its functional and serviceable. At some point, this motor is going to be pulled out when I do the 4wd conversion, and which point Ill completely re-do the wiring harness as well as all of the plumbing in an effort to clean up the looks but for now, its running better than it ever has and we're ready for the move to Texas next week!
