Q & A

What's in the Box

Races are won or lost at the starting line, so make sure you come out ahead with a High Performance Turbo 350-Turbo 400 Torque Converter. Whether you are looking for a street, strip, racing, or just plain heavy duty converter, these units will deliver lasting performance in your GM TH350 or TH400. With features like welded internals, oversized bearings, and hardened hubs, you can rest assured that these torque converters are of the highest quality possible. Made in the U.S.A.

  • For Turbo 350 and Turbo 400 transmission application
  • 2700-3000 stall - 10" diameter 
  • 1968-81 GM - 10-3/4" bolt circle

All stall ranges will vary depending on the engine setup, vehicle weight, and gear ratios.

Note: These converters will work with TH400 transmissions only if a dual bolt pattern flywheel is used.

Instructions (PDF)

To learn about how torque converters work and what to consider when purchasing one, check out our tech article. Choosing the Right Torque Converter. 

Item Details

Mildly modified S/B or B/B cars with high rise dual plane intake with 300-400 ft lbs torque, weighing 2900-3400 lbs, cam adv lift about .500" with 3.55-3.73 gears
These make use of 3/8-16" bolts.

Notes

  1. All advertised stall ranges will vary depending on your engine's setup and the weight of your vehicle. If your car is heavier than the recommendation, the stall speed will be higher. If the car is lighter, stall speed will be at a lower RPM.
  • Hardened Hub
    • Increased durability through the allowance of tighter tolerances and clean fit with transmission seals
  • Welded Impeller
    • Stronger pump fins to maintain stall speed over the life of the converter
  • Heavy-Duty Stators
    • Heat treated fins, sprag and race designed to efficiently handle high power loads
    • Stator fins are formed, not cut - cut stators can cause severe slippage
    • Rapidly dissipates heat - more power to the wheels
  • Welded Turbines
    • Pre-stressed before welding - more rigid construction
    • Heat treated splines
  • Aluminum Spacers
    • Incorporates aircraft quality aluminum spacers which handle higher loads than fiber spacers found in standard converters
  • Oversized Bearings
    • High strength stamped bearings absorb shock and extreme abuse better than standard waffle bearings
  • High Tech Welds
    • Positive-charged, military grade MIG welds for complete fusion of the metal

The stall converter for my 79 Camaro worked fine!!!

November 10, 2015
My cam for my 1979 Camaro was so large that my engine would cut off when I put it in gear. Now with a Speedway Motors 2700 - 3000 stall converter my flow masters on my vehicle sounds great and my converter and converter bolts were shipped to me faster than any other parts that I have ordered for my camaro. Thanks Speedway

After the transmission bolts are tight, check to see if the converter can turn freely. Push the converter into the transmission as far as possible. Using a ruler check the distance between the converter pad and the flywheel. Pull converter forward a minimum of 1/8", maximum of 3/16". Using flat washers remove any additional space between the converter and flywheel. This converter does not come with any spacers.

This Torque Converter p/n 109601, features a stall speed of about 2700 to 3000 in vehicles weighing about 2900-3400lbs and would work great in your Chevy powered Oldsmobile with the Comp Cams 280H grind cam. However, advertised stall ranges will vary depending on your engine's setup and the weight of your vehicle. If your car is heavier than the recommendation, the stall speed will be higher. If the car is lighter, stall speed will be at a lower RPM. This torque converter fits the TH350 or TH400 with dual bolt pattern flywheel only.

Thank you for your interest in our, 2700-3000 Stall TH350 Converter Item #: 109601. As with all street and occasional strip vehicles the owner will have to compromise on their wishes. No the engine will not have to turn 2700-3000 rpm when driving in town. But there will be some amount of slippage in the converter, causing added heat generated by the transmission. We highly suggest that you purchase the, HEAVY DUTY TRANSMISSION COOLER, Item #: 91023105, and mount it in front of the radiator to keep things cool when you drive in traffic. If your cam call for a 3000 stall converter it is because, if you purchase a converter with less stall, it will bog down the engine resulting in poor gas mileage and very poor throttle response. In other words you spent a lot of money and the car wont get out of its own way.

With your combination you should able to use the 2200 to 2600 stall converter 109600. The lower stall speed will be nicer to drive but the higher stall speed of this 2700 to 3000 would probably give slightly better performance at the track.

I have T Bucket that weighs about 1800 lbs. It is powered by sbc 350 with 9.5 to 1 compression, Edelbrock 2102 cam with 278/288 duration, .442 lift, Edelbrock RPM heads, 3.73 QC rear end, and TH350 transmission. I have heard you should use a higher stall speed converter so you don't override the brakes coming to a stop in a light weight car. Is the higher stall speed the way to go or should I stick with a stock or 2000 stall speed converter?

I am in the final stages of building a 68 Firebird convertible with a Pontiac 400 motor and TH400 transmission. It has a comp cam #51-222-4 with a gross valve lift of.470 and a duration .006 tappet lift of 270 on the exhaust (if I am explaining this correctly from the cam card), The rear end is a posi with 355 gears. Motor is probably around 470 to 490 HP. Going to be mostly a street car unless some kid pulls up next me in his Subaru with loud exhaust, then I may want to show him what the 70's and 80's were all about. Can you help me with a torque converter application? Thanks

With your camshaft, especially in a 400 engine, you can even run a stock converter. If you would like to have a slightly higher than stock stall speed then part number 109602 would work well for your combination.

With the lighter weight you can typically get by with a little bit less stall speed. I would go with this 2700 to 3000 stall for your combination.
