The big-block version of the Performer RPM pump, rated at 110 gallons per hour, which is enough to keep a healthy 454 fed at sustained throttle without going to an electric setup and its wiring, relay and noise. Pressure tops out at 6.0 psi, inside the range a four-barrel needle and seat is built to shut off against, so the bowls do not overflow at idle.
