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.

Product Features:

Absolutely The Most Accurate Way To Trigger The Ignition
The non-magnetic pickup cannot be false triggered.
Powerful magnets are embedded in a billet aluminum trigger wheel.

The Chevrolet HEI distributor is a favorite for muscle cars, street rods and even circle track racers. The integrated coil keeps under mount wiring clean, and for race cars, the idea of running one wire to the distributor keeps things simple. However, when it comes to performance, the stock HEI falls short. MSD answers the need for a strong, accurate and high performance HEI with our Pro-Billet HEI. The distributor is supplied with our digital HEI module and coil so there is plenty of spark energy combined with improved dwell and timing control. Tig welded on top of the distributor shaft is MSD’s adjustable centrifugal advance assembly. Three sets of springs and four stop bushings let you dial in up to 24 different timing curves to match your driving needs. Plus, there’s a vacuum advance for those concerned with economy. All of this is assembled around a precision and great looking CNC machined housing.

The Edelbrock 1405 Performer Series 600 CFM manual choke carburetor is a precisely tuned, quality-built carburetor that can handle the rigors of daily driving while delivering consistent, reliable street performance from day to day. Several characteristics make the 1405 Performer Series 600 CFM manual choke carburetor an outstanding street performer. The first one is that metering rods are utilized to transition between circuits. The carburetor is unaffected by engine backfires, which means that there are no power valves to blow out, and the rods can be changed in seconds without carburetor removal or fuel draining. Secondly, the carburetor has the unique ability to “hold a tune”, so once it is tuned, the carburetor stay’s tuned. What this means to you is that compared to other carburetors, the performance remains consistent and the calibration stays unchanged. The lightweight all-aluminum body features a two-piece body that resists warping and is compatible with gasohol and blended fuels. The simple tub-type bowls and rear-pivot floats all contribute to a carburetor that’s reliable, user-friendly and is easily tunable for miles and miles of trouble-free operation.

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.
