Converter 350/400 2700-3000 Stall

The ALLSTAR PERFORMANCE Converter 350/400 2700-3000 Stall is a torque converter engineered for street and strip performance in small-block and big-block Chevy applications. This converter is designed for builders and enthusiasts who want improved launch characteristics and faster acceleration off the line without sacrificing drivability on the street. Whether you're upgrading a stock transmission or fine-tuning a modified engine, a 2700–3000 RPM stall speed converter fills the gap between automatic and manual transmission feel, allowing the engine to build boost and power before engaging the load.

ALLSTAR's converter uses a precision-welded, internally balanced design that handles the thermal and mechanical demands of increased engine output. The 2700–3000 stall rating means the converter holds engine RPM at that threshold before the transmission's fluid coupling engages, allowing RPM to rise safely and maximize torque multiplication during acceleration. This stall window is ideal for engines with moderate to aggressive cam profiles and aftermarket power adders, providing consistent engagement without wheel spin or transmission shock. The converter's robust construction ensures reliability under repeated heat cycles and hard launches while maintaining smooth highway cruising characteristics when driven conservatively.

This converter is best suited for 350- and 400-cubic-inch engines paired with Turbo 350, Turbo 400, or comparable GM automatic transmissions. Street/strip drivers, weekend racers, and hot rod builders benefit most from the launch control and throttle response this converter delivers. Installation requires standard torque converter removal and reinstallation procedures; verify bell housing compatibility and transmission spline specifications before purchase. Proper transmission fluid type, cooler capacity, and engine tuning are critical to maximizing converter performance and longevity in daily or competitive driving.
