"The Edelbrock Performer RPM continues to impress me as a 6,000-rpm and under choice. As a dual-plane, the manifold produces more usable torque in the midrange with some of the larger-port heads than do most of the single-plane designs. At 5,700 rpm on a 455, and 6200 rpm on a 400, the party is just about over; but below these levels, it seems to increase the average torque output handsomely."
