Performer RPM Big Block Chevy W-Engine Large Port Intake Manifold

The Edelbrock Performer RPM #7159 intake manifold is designed to fit 1961-1965 Chevrolet 409 “W” big block engines with the Factory cast iron high performance heads (casting numbers ending in 690 or 583) or our new Edelbrock Performer RPM 409 heads (P/N 60809). This manifold will not fit the low performance 348 and 409 heads with small ports. The Edelbrock Performer RPM #7159 also features a natural aluminum finish for a classic look. For the ultimate "Made in USA" quality, every Edelbrock intake manifold is cast and machined in the USA.

Installation Notes:
• Recommended intake gasket: Edelbrock #7240 or Fel-Pro MS9788B
• Port exit dimensions: 2.39" x 1.16"
• Manifold Dimensions: A-4.35", B-5.54"
• Carb pad height: 4.62"
• Carburetor size (CFM) should be selected based on your specific engine combination.
• Use RTV sealant to properly seal end seals, such as Edelbrock High Temp Silicone sealant #1076, DO NOT USE END SEALS GASKETS.
• Hardened washers must be used with intake bolts to ensure proper torque and prevent galling of the aluminum.
• 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.
• To ensure maximum performance and a proper seal, Edelbrock gaskets which are specifically designed and manufactured for use with Edelbrock parts must be used.
• Proper installation is the responsibility of the installer. Improper installation will void your warranty and may result in poor performance and engine or vehicle damage.
