    With a .570" maximum lift, these Beehive™ Valve Springs from GM Performance are replacements for our GM 604 Crate engine. They allow big block engines to turn more RPM too. The unique Beehive™ shape handles valve train stress more efficiently to eliminate damaging harmonics and increases high RPM horsepower and durability. The oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valve train stress more efficiently and allow better heat dissipation for longer life. Because of the unique Beehive™ design, the valve train can handle more RPM and more aggressive cam profiles.

    Edelbrock's Super Victor (3500-8500 rpm) is a high-performance, feature-packed racing manifold for standard port location 23-degree cylinder heads. A taller profile with extra long runners that extend into the plenum offers increased volume. The cross-sectional area of the runners are tuned to complement the runner length creating substantial torque increases at 4500-5500 rpm.

    For Chevrolet 262-400 c.i. Small-Block V8. The Super Victor is designed for heads with standard port location and the runners match the "flat floor" entry of the latest 23° heads. It's about 1" taller than the Victor Jr., putting the carb pad height at 5-1/2" from end seals.

    • Slotted flange bolt holes to allow mating on decked blocks or milled heads
    • Rear water outlets allow custom cooling system routing
    • Flange above the intake ports is machined flat to provide a straight-line reference for port-matching layout
    • A boss for a distributor clamp has been added on the left side, for easier to access when timing an engine
    • Each runner has a nitrous boss to aid in fogger nozzle installation
