Tork Master 3000 Torque Converters - GM
B&M Tork Master 3000 Torque Converter, 1965-91 GM TH400, 1968-81 TH350.
High Stall Performance At An Incredible Value
B&M Tork Master Torque Converters are excellent all-around performance street converter. Even without a highly modified engine, these converters will give you better acceleration through a higher stall speed, allowing the engine to develop more torque at the time of initial acceleration. Tork Master Torque Converters are put together with new pump drive tubes, needle bearings when equipped on the original model, and new thrust washers.
- Highest quality-value priced street performance converters available
- Rated up to 350 HP/350 Ft-Lbs
- New precision steel pump drive tube
- Needle bearings where factory equipped
- New thrust washer between the turbine and cover
- Not recommended for higher performance big blocks or supercharged engines
- Not to be used with a transbrake
- Engines smaller than 350 cubic inches may not achieve indicated stall speeds
Choosing a B&M Torque Converter:
Car Weight: Street rods generally perform better using a 2400 RPM converter even with a mild motor due to the vehicle's lightweight. A 2000 RPM converter tends to require too much braking effort when idling but a 2400 RPM unit remains comfortable and efficient.
Stall Speed: Very mild street cars use a 2000 RPM stall speed unit. Most street-driven performance cars with 350 ft/lbs. of torque or more need a 2400 RPM unit. Cars with more radical small blocks (500 ft/lbs. of torque at 4500 RPM or higher) require a 3000 RPM converter. The more torque a motor puts out, the higher the resulting stall speed. Therefore most street performance big blocks would still use a 2400 RPM converter because they generally achieve 2600-2800 RPM. An engine smaller than 350ci might not achieve such stall speeds, which are based on an engine producing 230 ft/lbs. of torque at 2500 RPM.
Tork Master vs. Holeshot: Except for supercharged and nitrous engines, Tork Masters are a great value for most small block applications. Holeshots/Nitrous Holeshots should be used for all applications with 450 ft/lbs. of torque and all blown or nitrous applications. Holeshot converters are furnace-brazed with more sophisticated bearings. Thus they withstand much more torque and horsepower.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
