B&M Tork Master 2400 RPM Hi Stall Torque Converter for GM TH350 T350 Auto New

B&M offers a wide range of performance torque converters to fit almost everybody’s needs. All B&M converters are precision engineered, spin balanced and pressure tested. Performance converters are furnace brazed for strength.
The B&M environmental drive train development lab is a key tool used in the development of every converter designed by the engineering staff. Precision engineered, tested and the success at the track provide prove that B&M torque converters are the finest you can buy.

A higher than stock stall speed as delivered by this B&M 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. This high stall converter allows the engine to launch the car at a higher rpm where more torque is available.

The Tork Master is B&M's lowest cost performance torque converter. The Tork Master is an excellent all-around performance street converter. The best value priced street converters available, Tork Master converters come with a new precision pump drive tube and are pressure tested and fully balanced.

FAQ’s:

Why do I need a B&M torque converter?
The reason for considering a B&M torque converter boils down to performance. Higher stall speed is the key. A higher stall converter allows the vehicle to accelerate better from a dead stop and may provide tyre smoking performance.
What should I expect from a performance torque converter?
Strength and durability is an additional benefit if the converter is properly engineered. Furnace brazing is used to strengthen the converter internally for high performance, racing and heavy duty applications.

What is stall speed?
Stall speed numbers are listed primarily to rate the converter’s performance level. Typically, the number assigned, 2000, 2400, 3000 etc, lets you know what to expect from the converter. If a 2400 is selected, you should be able to footbrake stall the converter to about 2400 RPM. This should provide anywhere from 500 to 1000 more RPM to launch, or accelerate, the vehicle from a dead stop, as compared to the stock converter in the vehicle. This increase should substantially improve the acceleration capability of the vehicle. Lighter cars, 2800 lbs and under, typically stalls a little lower than the above mentioned numbers, therefore you should choose a converter with a higher stall number for optimum performance.

How does the engine’s camshaft affect the torque converter’s performance?
The camshaft will affect the torque curve of the engine, which will affect the performance of the converter. For example if your 350 cid engine produces 230 lb.ft. of torque at 2400 rpm a B&M HoleShot 2000 converter will produce 2000 rpm stall speed. If you install a 268-degree cam into this engine you will raise the torque curve and at 2400 rpm your engine will produce less torque. Thus the 2000 stall converter will only stall at 1800 or less. However with this new cam the engine will make much more power above 3000 rpm. Keep in mind when the torque curve of the engine is raised you will need more stall speed in the converter to allow the vehicle to accelerate at low rpm (below 3000). A good rule of thumb for advertised cam durations up to 248 degrees, a 2000 or 2400 stall converter is a good choice. Advertised cam durations up to 268 degrees, a 2400 or 3000 stall converter is a good choice. Advertised cam durations over 272 degrees, a 3000 to 3600 stall converter is a must.

Fitment notes:

• Suitable for GM TH350 & TH400 3 Speed Automatic Transmission.
• Suitable for use with Holden 308, GM/Chev 283 307 327 350 engines fitted with TH350/TH400 Transmission with 10.75” bolt circle converter.
• They should not be in supercharged or turbocharged applications.
• Stall speeds are based on an engine producing 230lb/ft of torque at 2500 RPM. Engines with more torque will stall higher and less torque will stall lower than indicated.
