    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.

    Designed for 1986 and earlier 262-400 cubic-inch Chevys, the Performer EPS dual-plane manifold is optimized to deliver superior performance over other low-rise dual plane manifolds. This small-block Chevy manifold has a runner design that's "tuned" for peak torque around 3500 rpm on a 350-inch engine and it produces power from off-idle to 5500 rpm.

    Dyno tests showed gains of 5 hp and 9 ft/lbs of torque over the standard Performer manifold on a 350 Chevy. From 3000 to 4500 rpm, the increases averaged 5+ ft/lbs. of torque for more performance where you need it most.

    IMCA racing approved.
