The FTI Performance 9.5-inch Billet Street Racer torque converter for TH350/TH400 GM transmissions offers a 3200 rpm stall for drivers who use their car as a daily and a weekend racer. Engineered in-house, these units feature TIG-welded, furnace-brazed fins, a heavy-duty race sprag and a hardened steel impeller; non-lockup versions add triple Torrington bearings and a billet front cover, with each unit pressure-checked and computer-balanced.
