If you do not feel comfortable performing this installation, it is recommended to have the installation completed by a qualified mechanic. If you have any questions, please call our Technical Hotline at: 1-800-416-8628, 7:00 am - 5:00 pm, Pacific Standard Time, Monday through Friday. IMPORTANT NOTE: 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. DESCRIPTION: Edelbrock Performer intake manifolds are designed for street-performance Ford 351-M/400 engines operating in the idle-5500 RPM range. The Performer 400 EGR intake manifold is a direct replacement for the factory intake manifold and is 50-state street legal on applications using the OEM 2-bbl carburetor and EGR system with the supplied EGR spacer (See “EGR SYSTEMS” section below). In off-highway applications, this intake manifold is part of a Total Power Package that can be completed with the use of dyno-matched Performer-Plus camshaft #2172, springs, chain set, carburetors and related parts specifically designed to give you maximum results. Please see to the Edelbrock catalog for details.

Carburetor size (CFM) should be selected based on your specific engine combination. Consult your engine builder or contact our Technical Hotline at: 1-800-416-8628 for assistance. If a manual choke Performer Series Carburetor is used and electric choke is desired later on, Performer Series carburetors can be converted to electric choke using Electric Choke Kit #1478. Manual choke Thunder Series carburetors CAN NOT be converted to electric choke. • THROTTLE BRACKETS: The throttle and kickdown bracket on some vehicles may require modification to fit. When using Edelbrock carburetors, use #1493 or 1847 throttle plate kit to line up the stock throttle bracket to the Edelbrock carburetor throttle lever.

Due to material deterioration over time, internal leakage of vacuum and oil may occur. INTAKE MANIFOLD 3771 REFERENCE (None) RECOMMENDED GASKET Fel-Pro #MS96020 or OEM valley plate NOTE: To ensure maximum performance and a proper seal, Edelbrock gaskets which are specifically designed and manufactured for use with Edelbrock parts must be used. • EGR SYSTEMS: Edelbrock EGR-equipped Performer manifolds are intended as a direct functionally identical replacement for their O.E.M. counterparts. All exhaust emissions or emissions related stock components are intended to be retained and functional.. EGR systems are used on most 1972 and later model vehicles. Check local laws for requirements. Edelbrock EGR adapters are designed to accept various OEM EGR valves. However, you must ensure proper EGR port alignment before securing the valve to the adapter. Match the large (3/8”) and small (5/16”) mounting bolts and holes in the adapter and the valve for proper EGR flow direction. Be sure to use a new OEM gasket when installing the EGR valve. See Figure 1 for proper EGR adapter plate installation. 5/16” Hole 3/8” Hole EGR Adapter Gasket • Intake Manifold PREP AND TUNING FOR POWER: 1. Due to design, the fuel / air mixture and cylinder charging is very efficient with Performer manifolds. Generally speaking, the stock jetting for the OEM or a Performer Figure 1 Series or Thunder Series carburetor will not need changing. Specific applications may show an increase in power by tuning the fuel mixture. 2. Performer manifolds deliver excellent driveability and power utilizing the factory OEM distributor settings. Specific applications may benefit from resetting the initial timing + or -2° from the factory specifications. Aftermarket distributor curve kits may be used with Performer series intake manifolds. 4. Installation of aftermarket headers, camshafts or both with an Edelbrock Performer RPM series manifold may lean carburetor calibration. Should this condition occur, recalibrate with a richer jet. • CAMSHAFT AND HEADERS: Performer Series manifolds are compatible with aftermarket camshafts and headers designed to work in the idle5500 RPM range. For Off-Highway applications, Edelbrock has developed a dyno-matched camshaft, Performer-Plus #2172, which is ground specifically for use with the Performer 400 intake manifold. Header primary tube diameter should be 1-5/8". INSTALLATION PROCEDURE 1. Use only recommended intake gaskets set when installing this intake manifold. 2. Fully clean the cylinder head intake flanges and the engine block end seal surfaces. 3. Apply Edelbrock Gasgacinch sealant P/N 9300 to both cylinder head flanges and to the cylinder head side of the gaskets, allow to air dry, and attach the intake gaskets. 4. Do not use cork or rubber end seals. Use RTV silicone sealer instead. Apply a ¼" high bead across each block end seal surface, overlapping the intake gasket at the four corners. This method will eliminate end seal slippage. 5. Install the intake manifold and hold-down bolts. Torque all of the manifold bolts in two steps by the sequence shown in Figure 2 to 25 ft/lbs. For ease of installation, we recommend Intake Manifold Bolt Kit #8574. Figure 2 - 351-M/400 Ford Torque Sequence Torque Bolts to 25 ft/lbs.
