It runs a 1,600 to 2,200 RPM stall, close to stock, for a mild street feel. Internally it uses the factory 12 in core, a 30-spline CNC-machined turbine hub, a hardened chrome moly impeller hub, Torrington-style encased bearings, and a modified extreme-duty stator. Every unit is leak and pressure tested, digitally balanced, and made in the USA. It is a non lock-up converter and will not interchange with the lock-up TH350C.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSeries: Night Stalker\u003c\/li\u003e\n\u003cli\u003eTransmission: GM TH350 (also TH400 with proper flexplate; PG 30-spline)\u003c\/li\u003e\n\u003cli\u003eStall Speed: 1,600-2,200 RPM\u003c\/li\u003e\n\u003cli\u003eCore: 12 in (factory)\u003c\/li\u003e\n\u003cli\u003eBolt Circle: 10.75 in\u003c\/li\u003e\n\u003cli\u003eTurbine Spline: 30 (CNC-machined)\u003c\/li\u003e\n\u003cli\u003eImpeller Hub: Hardened chrome moly\u003c\/li\u003e\n\u003cli\u003eBearings: Torrington-style encased\u003c\/li\u003e\n\u003cli\u003eStator: Modified extreme duty\u003c\/li\u003e\n\u003cli\u003eCrank Pilot: 1.703 in\u003c\/li\u003e\n\u003cli\u003eBolt Size: 10mm x 1.5 (Class 10+)\u003c\/li\u003e\n\u003cli\u003eAnti-Balloon Plates: No\u003c\/li\u003e\n\u003cli\u003eLock-Up: No (will not interchange with TH350C)\u003c\/li\u003e\n\u003cli\u003eBalance: Digitally balanced\u003c\/li\u003e\n\u003cli\u003eBuild: Leak \u0026amp; pressure tested; made in USA\u003c\/li\u003e\n\u003cli\u003ePart Number: 47011\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWARNING: This product can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm.
