The Nitrous Holeshot 3800 stall converter is an excellent choice for vehicles with engine modifications, particularly big cams that tend to reduce low end power and torque. The higher stall speed of this converter will launch the car in a higher rpm range where more torque is readily available, resulting in quicker acceleration. Nitrous Holeshot converters feature furnace brazed impeller and turbine, new precision steel alloy pump drive tube, new heavy duty needle bearings between the stator and impeller (not a thrust washer) and needle bearings between the stator and turbine. Other features include dual pattern 10.75 and 11.50 inch drive lugs, a new turbine hub, new springs and rollers in the stator and anti-balloon plates. The anti-balloon plates will allow these converters to stand up to the instant horsepower a nitrous plate system delivers. 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.\u003ch5\u003eResources\u003c\/h5\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/www.catalograck.com\/ImgVD\/BMA\/BM_Warranty.pdf\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003ch5\u003eSpecifications:\u003c\/h5\u003e\u003cbr\u003e\u003ctable class=\"descr-table\" border=\"0\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnti Balloon Plate\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutomotive Item Grade\u003c\/td\u003e\n\u003ctd\u003eHigh Performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBolt Circle Diameter\u003c\/td\u003e\n\u003ctd\u003e10.750 in.\/11.500 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrank Pilot Diameter\u003c\/td\u003e\n\u003ctd\u003e1.710 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_ASC\u003c\/td\u003e\n\u003ctd\u003eHolley Performance Emission Code 5: This part is legal for sale or use on Emissions Controlled Vehicles; Uncontrolled (Non-Emissions Controlled) Vehicles; and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_ASM\u003c\/td\u003e\n\u003ctd\u003eFits vehicles with GM TH400; TH425; TH375\/TH350 Automatic Transmissions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DEF\u003c\/td\u003e\n\u003ctd\u003eAutomatic Transmission Torque Converter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DES\u003c\/td\u003e\n\u003ctd\u003eNitrous Holeshot 3800 Torque Converter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_EXT\u003c\/td\u003e\n\u003ctd\u003eNitrous Holeshot 3800 Torque Converter; 3500 - 3800 RPM Stall; 1.71 Crank Pilot;\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eBetween Stator and Turbine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eFurnace Brazed Impeller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eFurnace Brazed Turbine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eHeavy Duty Needle Bearing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eNew Springs\/Rollers In Stator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eNew Turbine Hub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eSteel Alloy Pump Drive Tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_INV\u003c\/td\u003e\n\u003ctd\u003eCNVRTR; TH350; NITROUS HOLESHOT 3800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_KEY\u003c\/td\u003e\n\u003ctd\u003e20485;b\/m;bm;b and m;torque;converter;torque converter;nitrous;holeshot;3800;gm;th400;th425;th375;th350;automatic;transmission;drivetrain;performance;high performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_LAB\u003c\/td\u003e\n\u003ctd\u003eMade In Logo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_MKT\u003c\/td\u003e\n\u003ctd\u003eB\u0026amp;M Nitrous HoleShot 3800 stall for GM 1965 to 1991 TH400, TH425, TH375 and 1968 to 1981 TH350, TH375B (not TH350C.)

These are serious converters for serious performance street cars. To prevent contamination left from worn parts being circulated in your new components causing premature wear, we strongly recommend protecting your investment by adding a B\u0026amp;M transmission cooler with all new transmission installations.
