Speedmaster PCE376-1079: Distributor, 7000 Series, Magnetic Pickup, Vacuum and Mechanical Advance, Chevrolet, Small Block, Big Block, Each - Procomp Electronics 7000 Series distributors are the perfect upgrade for your outdated and worn out stock version. To install one of these distributors, just hook up two wires and you are ready to run! A maintenance-free magnetic pickup inside the distributor triggers a state-of-the-art ignition module under the chrome cover. The increased output of this self-contained ignition easily outperforms stock ignitions and helps to smooth out the power-band from idle to high-rpm. For stability and endurance, an oversize steel shaft spins in a top mounted sealed bearing while an extra-long sentried bushing guides the shaft at the bottom of the housing. To increase gas mileage, we included a vacuum advance assembly, and you can tailor the mechanical advance curve to suit your engine. For excellent street performance, Procomp Electronics 7000 Series distributors are the best choice! Order the model recommended for your vehicle and engine application.
