HoleShot 3600 for GM 1965 to 1991 TH400, 425, 375 and 1968 to 1981 TH350, 375B (not 350C) APPLICATION: HoleShot 3600 for GM 1965 to 1991 TH400, 425, 375 and 1968 to 1981 TH350, 375B (not 350C) A higher than stock stall speed as delivered by the Holeshot converter will provide several advantages and benefits in vehicles with modified engines. 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. Dual pattern drive lugs on some GM Holeshots. New turbine hub. New springs and rollers in stator.

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:

Replacement crank trigger wheel for small block Chevy
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

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.
