MSD’s Ready-to-Run Ford distributors are the perfect upgrade for bulky Duraspark systems or ancient breaker point models. All you need to do is drop it in the engine, connect three wires and fire the engine. Each distributor features an ignition module that produces a powerful inductive spark to improve combustion of the fuel mixture resulting in quick starts, smooth idle and increased performance. The billet aluminum housings of these distributors are 5/8 In. smaller in diameter to accommodate induction setups and tight engine compartments. A maintenance-free magnetic pick-up is responsible for triggering the high voltage sparks while a sealed ball bearing guides an oversized shaft. Beneath the bolt down cap and MSD race rotor you’ll find MSD’s accurate mechanical advance assembly. Different advance springs and stop bushings are supplied so you can easily tune a curve to match your needs. Plus, there is a vacuum advance canister to increase economy on long drives.

Product Features:

Equipped w/Steel Gear
CARB E.O. Approved
Does not require an MSD Ignition Control

The result is a product that meets and exceeds the expectations of today’s engine builders and racers.

Product Features:

Seat pressure: 115 lbs. @ 1.700″, Open Pressure: 284 lbs. @ 1.200″

COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The umbrella seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop Teflon seal is used. The umbrella seals require no machining, but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.

Product Features:

Work with stock guides and 11/32″ valve stem diameter
Valve stem oil seals keep unwanted oil from entering the combustion chamber
Several different types of valve seals are offered

Our DynaForce starter is designed to crank over the highest compression engines on a hot day in Death Valley. Not that too many race cars are sitting in Death Valley, but it’s good to know that you have the oomph to make it happen. The DynaForce starter features all new components beginning with a three horsepower motor. This power is used to crank over the reduced 4.4:1 gear set to deliver great torque to the engine’s ring gear to get the engine turning. The downsized housing clears most headers and oil pans, but just in case, we made the billet mount so it can be clocked in different positions to help in tight applications. The assembly is powder coated MSD red and will stay looking good, even though it’s underneath your car.
