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.

    Crank Trigger Kit; Small Block Chevy; 6? Balancer

    from

    $461.99
    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:
    • 6.25 in. Diameter
    • 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.

    MSD Ignition – Wire Set; Black Super Conductor; Small Block Chevy; HEI (Part No.31353)

    Wire Set; Black Super Conductor; Small Block Chevy; HEI

    from

    $143.99
    The MSD 8.5mm super conductor wire is the performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference. In a single 12 inch length of super conductor wire there is only 40 – 50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) or choke. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. Available in universal kits and bulk lengths.

    Product Features:
    • Custom Fit For Make And Model Listed
    • Wires Are Pre-Cut To Exact Specifications
    • Bolt-on Performance
