Installation Time: 4 Hours
Please study these instructions carefully before beginning this installation. Most installations can be accomplished with common tools and procedures. However, you should be familiar with and comfortable working on your vehicle. 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 or e-mail us at Edelbrock@Edelbrock.com.
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: The Performer 5.0 intake manifold is designed for 1986-1995 5.0L Mustangs and passenger vehicles (will not fit trucks). It is ideally suited to street/strip applications with an RPM range of idle-5500 RPM. The manifold features a removable plenum cover allowing access to runners for modification if desired (not necessary for operation below 6000 rpm), and CNC port matched upper and lower manifolds for maximum flow efficiency. Manifold WILL NOT clear factory 1994-1995 Mustang strut tower brace. Use Edelbrock Strut Tower Brace #5225.
Emissions Systems: This manifold is intended as a direct replacement for the factory intake manifold. All emissions related factory components are to be retained and functional. The manifold is, therefore, legal for street use in all 50 states, and no C.A.R.B. E.O. number is required. Check local laws for requirements.
ACCESSORIES & INSTALLATION ITEMS: Major recommendations are listed below. See our catalog for details. To order a catalog, call (800) FUN-TEAM, or visit www.edelbrock.com.
THROTTLE BODY RECOMMENDATIONS:
|APPLICATION||THROTTLE BODY||PARTS REQUIRED FOR INSTALLATION|
|1986-1993||3824 (65mm)||65mm EGR Plate #3827|
|3825 (70mm)||70mm EGR Plate #3828|
|3826 (75mm)||75mm EGR Plate #3829|
|1994-1995||3844 (65mm)||Throttle Body Adapter #3835 and Mustang EGR Supply Spacer #8025|
|3845 (70mm)||Throttle Body Adapter #3835 and Mustang EGR Supply Spacer #8025|
|3846 (75mm)||Throttle Body Adapter #3835 and Mustang EGR Supply Spacer #8025|
NOTES:A 65mm throttle body is recommended for use with the Performer 5.0 intake manifold on otherwise stock engines, while a 70mm throttle body is recommended for most street/strip applications as a part of our Performer Power Package. 75mm throttle bodies should be used in higher horsepower applications (Port matching required). The air valve (throttle body) location is 0.50 forward and 0.30 higher than the stock location.
If parts required for installation are unavailable locally, contact Edelbrock directly.
CAMSHAFT AND HEADERS: Performer Series manifolds are compatible with aftermarket camshafts and headers designed to work in the idle-5500 RPM range. Edelbrock has developed a dyno-matched, street-proven camshaft, Performer-Plus #3722 (For Mass-Air engines only), Tubular Exhaust Systems #6845, and Cat-Back exhaust system #5645 or #5646, which are suitable for use with the Performer 5.0 intake manifold on 1986 through 1993 Mustangs. Consult your dealer, Edelbrock catalog, or Edelbrock Technical Hotline for applications.
CYLINDER HEADS: Manifold should be used with modified or high performance cylinder heads to achieve full power potential. Edelbrock Performer 5.0L cylinder heads are fully assembled, ready to run cylinder heads that are designed to work with this intake manifold.
GASKETS: Do not use competition style intake gaskets for this street manifold. Due to material deterioration over time, internal leakage of vacuum, oil, and coolant may occur. Replacement plenum cover and manifold top to manifold bottom gaskets available as Edelbrock #3832. OEM Ford gaskets will not fit.
|INTAKE MANIFOLD||REFERENCE||RECOMMENDED GASKET|
|3821||(None)||Edelbrock #7220 Port: 1.20 x 2.00, .060 Thickness|
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.
NOTE: Local emission laws must be checked for legality of any tuning or ignition changes.
Before Beginning: This installation can be accomplished using common tools and procedures. However, you should have a basic knowledge of automotive repair and modification and be familiar with and comfortable working on your vehicle. If you do not feel comfortable working on your vehicle, it is recommended to have the installation completed by a qualified mechanic. Keeping a service manual for your specific vehicle on hand for reference is helpful.
REMEMBER: WHEN WORKING AROUND GASOLINE, DO NOT SMOKE, and KEEP ALL OPEN FLAMES, SPARKS AND OTHER SOURCES OF IGNITION AWAY FROM THE WORK AREA. Failure to do so can result in a FIRE or EXPLOSION.
IMPORTANT: PCV valve baffle must be installed before manifold is bolted to engine!
