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. Dyno tests proved that the EPS 800 carb outperformed a Holley #3310 carb out-of-the-box by 26 ft-lbs. of torque and 22 hp on a small-block Chevy engine equipped with an Edelbrock Performer RPM power package

    MSD Ignition – Blaster 2 Coil: High Performance Ignition Upgrade (Part No.8202)

    Blaster 2 Coil: High Performance Ignition Upgrade

    from

    $49.99
    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.

    Product Features:
    • Improved output coil for electronic ignitions
    • Works w/Blaster Ignition Or MSD 5/6/7 Series
    • Ballast Resistor Required If Used w/Stock Points Ignition

Many modifications, particularly big cams, tend to reduce low end power and torque. The high stall converter allows the engine to launch the car at higher rpm where more torque is available. The Holeshot is generally a very good choice for the typical street machine that is looking for better launch capability and more strength. Street rods with modified engines will also benefit from a Holeshot converter. If your vehicle is equipped with a plate type nitrous system, you will need a Nitrous Holeshot!! Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. Furnace brazed impeller. New precision steel alloy pump drive tube. New heavy duty needle bearing between stator and impeller (not a thrust washer). Needle bearing between stator and turbine. Furnace brazed turbine.
