The Edelbrock 1406 Performer Series 600 CFM electric 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 1406 Performer Series 600 CFM electric 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.

If you are looking to upgrade your stock coil, or want to compliment the performance of your MSD blaster ignition, MSD 5, 6 or 7, the blaster coil line is the right choice. All of the blaster coils are designed for improved spark output. Special 100:1 windings are used to provide maximum build-up of voltage. These windings are held secure and kept cool in an oil filled metal canister. The tower assembly is molded of durable alkyd material due to its high dielectric characteristics while wide spaced brass primary terminals prevent the possibility of spark. There are several versions of the blaster coil available. All of them have the same internal specifications, but have different housings or components. Each blaster coil can be used with a stock ignition, blaster ignition, MSD 5, 6 or 7 ignition control. Most late model vehicles with electronic ignitions do not require a ballast resistor, check your ignition and manufacturers specifications to determine if a ballast is required in your application.
