1974 Ford E-300 Econoline Torque Converter and Related Products

Hays Performance Drivetrain is proud to announce Twister 3/4 Race Performance Torque Converters. These NEW torque converters are a perfect addition to Hays product line of performance flexplates, clutches, and flywheels. The 3/4 Race torque converter is the first series being brought to market and is intended for street/strip combinations, with various RPM stall speed offerings to accommodate any mixture of modifications including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss.

Product Features:

• 3/4 Race series converters are built, tested, and proven to support up to 650 HP
• State of the art Spray Welding process is used in select areas. Spray Welding provides clean, strong and consistent fusion while also increasing strength through hardening from higher process temperature
• Each converter is hand-built and inspected in every step of assembly to ensure top of the line quality
• All HAYS converters are internally welded compared to brazing. Testing has shown welding provides longer converter life while also enhancing consistency
• Heavy duty Torrington bearings are used for greater strength and durability
• Stators are chosen with high flow vents and channels to promote cooling in heat producing higher horsepower applications
• Increased horsepower and acceleration due to a weight saving, one application design. Almost all HAYS converters are built for one application to reduce weight compared to a multi-bolt pattern converter.
• 3/4 Race series converters are offered in several different stall speeds for GM, Ford, and Chrysler transmissions
• Industry leading Tech Support Team is available to provide assistance with stall speed selection

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. Due to torque converter core availability, the actual converter size may vary but performance functionality will be as advertised.
