Welcome back to our coverage of Project Power Laggin’! Follow along as we take a tired 1979 Dodge W150 Power Wagon we found in Central Maine and transform it from a derelict roadside attraction to a dependable, powerful weekend workhorse that lives up to it’s given name! In this installment, we ditch the ancient Mopar ignition system for a modern Holley HyperSpark control box, coil, and distributor!
During our last installment of our ongoing EFI conversion series, we bolted on a new Weiand Stealth intake manifold for the MSD Atomic EFI 2 throttle body to sit on. As part of the ensemble of parts we are throwing at the truck, we opted to grab a new Holley HyperSpark ignition box, distributor, and coil. But before we install those, let’s talk about the current ignition system a bit.
Ditching the stock Mopar ignition box, distributor, coil, and ballast resistor may be a shock to the old school guys, but the reality is that the modern HyperSpark components are more reliable and provide cleaner, better spark to the engine. With EFI, this also helps increase efficiency and dependability. Not having to play the “Guess Which Old Ignition Part Failed This Time” game is something we were really looking forward to! Not only that, but paired with our new Atomic 2 fuel system, it’s a plug-and-play deal with some minimal wiring needed to make it all work together. And the consumables themselves, like the cap, rotor, wires, and coil can all be found at just about any auto parts store in every town in America. In fact, we’d be willing to bet that it’s even EASIER to find these parts in stock on a shelf than something for a 40+ year old Dodge pickup. Remember, it’s not 1987 anymore. You’d be surprised at how many parts for this old rig are either special order or the dreaded “No Longer Available” these days.
With that said, we still need to finish up wiring everything to the truck and install the rest of our fuel system components and see if all of this work results in a running truck. We’ll tackle that next time, so stay tuned!
