Mallory’s UNILITE (R), and magnetic breaker less ignition modules are self contained module assemblies which have no moving parts to wear out. Using Mallory’s time tested breaker less ignition circuit, combined with modern surface mount thermal-clad construction, these ignition modules can drive both OEM and high performance ignition coils. For best results always use a Mallory PROMASTER coil or a Mallory chrome electronic ignition coil. These are also an excellent choice for triggering one of the Mallory HyFire series of electronic ignition controls. Hookup is as easy as a three wire connection.

For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD flying magnet crank trigger system does exactly that by using magnets embedded in an aluminum wheel. The MSD flying magnet crank trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This flying magnet design produces accurate trigger signals and the non-magnetic pick-up cannot be false triggered. Each flying magnet crank trigger includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver’s side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The adjustable bracket provides a wide range of timing adjustment and spacers are included. These systems will trigger MSD 6, 7, 8 and 10 series ignitions and all MSD timing accessories.

Absolutely The Most Accurate Way To Trigger The Ignition

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.

Our unique Multi-Layered steel head gasket embossment formation process optimizes the embossment radius, reduces stress points, enhances gasket conformability, and provides uniform clamp load distribution. This all results in superior surface contact between block and cylinder head. All head gasket layers/spacers go through an additional process to significantly reduce forming induced stress. Advantages are reduced brittleness in material, increased flexibility and deformation retention. This stabilizes the gasket, resulting in reduced cylinder bore distortion and improved combustion seal fro the extreme cylinder pressures found in high compression, supercharged and turbocharged applications. A proprietary polymer coating ensures the micro-seal of engine coolant and oil fluids.brbrA typical MLS head gasket requires a smoother (30Ra) surface finish than composite head gaskets. Mr. Gasket’s proprietary polymer coating will seal a surface finish twice as rough (60Ra) as a typical MLS head gasket. For high performance street, drag race and oval track use.

Product Features:

Gasket bore – 4.030 inch: Compressed thickness – .040 inch
Manufactured from 3-layer premium grade stainless steel and state of the art laser cutting
