TCI Automotive Torque Converter 241000; Street Fighter 3000 to 3400 30 Spline Non-Lockup for GM TH350, TH400

Designed with the street/strip racer in mind, this torque converter benefits more radically prepared street machines (those with performance cams, aftermarket carburetors and higher compression ratios) to bring the launch RPM in line with the performance enhancements. The StreetFighter allows you to take advantage of horsepower gains found in higher RPM ranges and provides up to 1500 RPM increase in stall over stock.
