Finally, An SBC Intake Engineered For Today's Applications

The RHS Single Plane 23° Aluminum Intake Manifold is engineered specifically to port match fit RHS Small Block Chevy cylinder heads. Additionally, this manifold is the only one designed with bolt machining to fit all versions of Small Block Chevy cylinder heads, including classic originals, Vortec GM heads and late model perimeter corner vertical bolt style crate engine heads. It provides the power and strong torque curve throughout the mid-RPM range that is required for performance street, circle track and drag race applications up to 434c.i. The manifold also features auxiliary water ports, integral water crossover and dual sided distributor mounting points. Female pipe fittings at all four corners allow external water lines for reverse cooling applications.

Integral Sensors - Injectors Angled Directly At Valves - Uses LS-Style Sensors & Injectors

RHS and sister company FAST teamed up to design the revolutionary port fuel injection version of these manifolds. Unlike the competition, the EFI manifold features port angle optimized injector mounting and machining features. FAST engineers laid the injectors down on an angle that points injectors directly at the valve stem. Additionally, the EFI manifold features integral air temp and MAP sensors improving function, fitment and packaging.

Information Summary:

  • FAST red annodized fuel rails & hardware - Use common, standard (2.550"" o-ring to o-ring) injectors or short (1.480"" o-ring to o-ring) LS3/LS7 injectors

  • Fits all ""Gen 1"" SBC heads ('55-'02) - From classic originals to Vortec to late-model perimeter corner vertical-bolt crate engines

  • Port angle optimized injector mounting - Injector holes are machined so injectors are angled directly at valves

  • Integral air temp & MAP sensors improve function, fitment & packaging - Uses LS1-Style MAP & air temp sensor

  • Strong torque curve throughout mid-RPM range - Excellent for performance street, circle track & drag race engines up to 434c.i.

  • 4150 flange works w/ aftermarket 4BBL throttle bodies or a late-model throttle body adaptor elbow of your choice

  • Dual sided distributor mount - Auxiliary fittings at all four corners allow external water lines for reverse cooling


*Depending on the cylinder heads/valve covers being used, minor clearancing to the intake manifold may be required.

Some parts are not legal for use in California or other states with similar laws/regulations
