Tune Up Kit

If you've never worked on one of these trucks, let us tell you it is a bear to get back to the distributor. Thanks to the set-back nature of the engine, the tall barrel-shaped intake, and the pseudo cab-forward design, the distributor is entirely under the cowl and buried in vacuum and electrical lines. While we had the plenum off, we looked at the cap, and like many other things, it needed attention and we wondered if it was the original cap. We replaced the cap, rotor, wires, and coil with a Summit Racing Tune-up Kit (p/n SUM-867815CR with p/n HYP-4066) and a set of eight E3 spark plugs (p/n ETP-E3-48) in an attempt to maximize mileage and performance out of our big V-8.
