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 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 or Turbo 400 transmission applications
  • 2200-2600 stall - 12" 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)

Item Details

Near stock mildly modified S/B or B/B cars with 300 ft lbs torque, weighing 3200-3800 lbs.
Makes 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

Works!

February 07, 2016
Raised my stall compared to what it was before, 1500 to 2000. It was for a 1932 Chevy 5 Window Coupe, mild 350 Small Block, and 4:11 gears. With converters it is always hard to know what the final stall will really be. Was hoping for a little more but for the price it works for me...
Pros:
  • Quality For A Great Price
  • Easy Upgrade
Cons:
  • Include The 3 Bolts
Yes, I recommend this product.

For most mild street cams this converter would work fine for you. If you have a more radical street cam then you may need more stall and a converter such as 109601 or 109603.

No, this TH350-TH400 torque converter is for stock or lightly modified small and big block engines with 300 foot pound of torque weighing 3200-3800 pounds. This should not be used with lock up style transmission.

I would recommend the 2000 to 2200 stall converter 109602 for your combination as long as your Goodwrench 350 still has the stock camshaft.
