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.

Edelbrock – Performer 1406 Carburetor: 600 CFM, 4 Barrel, Square Bore, Electric Choke Inlet (Part No.1406)

Performer 1406 Carburetor: 600 CFM, 4 Barrel, Square Bore, Electric Choke Inlet

from

$428.99
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.

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.
