The TCI Circlematic Torque Converter is an 11-inch stock-appearing converter for Powerglide-equipped circle track cars, with an advertised 1800-2100 RPM stall. It suits applications with 350 cubic inch and larger engines weighing more than 3000 pounds. The lower positive lock-up stall reduces slippage for stronger off-the-corner acceleration, and a heavy-duty stator, furnace-brazed fins and certified stall speed support consistent lap times. A higher-stall option is offered under 741115.
