LOS ANGELES - Dynamometer tests prove that a strategically positioned change in the primary tube broadens the engine's overall torque curve. After installing Hedders, a small-block Chevy engine of 5.7-liter piston displacement will experience a "torque boost" in the 2800 to 3200 and 3600 to 4000 RPM ranges. The result is a solid increase in low RPM towing and pulling power, increased RPM recovery rates upon gear shifts, and more power during downshifts for passing?all these gains with no loss of torque during the mid-RPM range. These hedders work equally well on street-strip applications and trucks.
