The Edelbrock Performer #21011 intake manifold is designed for street 1955-86 small-block Chevys. Edelbrocks Patented Dual-plane, low-rise design with a 180-degree firing order greatly improves torque over a wide rpm range for excellent throttle response from off-idle through 5500rpm. Not for 1987 and later cast iron or Chevy Bowtie heads. Will fit 1987 and later stock aluminum heads. The Edelbrock Performer #21011 also features a polished aluminum finish for a brilliant shine and classic look. For the ultimate "Made in USA" quality, every Edelbrock intake manifold is cast and machined in the USA.

• Sealant must be used on intake bolt threads if the threads extend into lifter valley or coolant passage.
• NPT/Pipe thread fittings require the use of Teflon tape or paste on threads to ensure proper seal.
• DO NOT OVERTIGHTEN NPT/Pipe fittings, this may cause the aluminum to crack around the fitting boss. NPT/Pipe thread is a tapered thread.
• Hardened washers Must be used with intake bolts to ensure proper torque and prevent galling of the aluminum.
