• PLEASE study these instructions, and the General Instructions, carefully before installing your new manifold. If you have any ques-

tions or problems, do not hesitate to call our Technical Hotline at: 1-800-416-8628.

• EGR SYSTEM: This manifold will not accept stock EGR (exhaust gas recirculation) equipment . EGR systems are used on some

1972 and later model vehicles and only in some states. Check local laws for requirements. Not legal in California on pollution-con-

trolled motor vehicles.

• MANIFOLD: The Edelbrock Performer RPM Q-Jet manifold has been designed for 262-400 c.i.d. small-block Chevrolet engines with

high performance spread-bore Q-Jet carburetors only. It is not for stock calibration, emissions style Quadrajets which are too lean for

high performance applications. The manifold accepts late model water neck, air conditioning, alternator and H.E.I. ignition systems.

Use the recommended electric or manual type choke carburetors only. This manifold is recommended for street high performance and

race vehicles only. The Performer RPM Q-Jet manifold provides good low rpm response for street performance vehicles and increases

performance above the 5000 rpm range. It also provides horsepower and torque increases within the listed rpm range, when used with

any mix of aftermarket equipment available for vehicles operating within that range.

• ACCESSORIES & INSTALLATION ITEMS: Major recommendations are listed below. However, due to the variety of years,

makes and models to be covered, please review each part listed in the Installation Items section of the Edelbrock catalog to decide

whether more items are required for your specific vehicle than are mentioned in these instructions.

• POWER PACKAGE: Edelbrock Performer RPM manifolds are part of a total Power Package System that can be completed with the

use of dyno-matched Performer RPM camshaft #7102, valve springs #5703, True Rolling timing set #7800 or Accu-Drive gear drive

#7890, carburetor #1910 and related parts specifically designed to give you maximum results.

• CARBURETOR RECOMMENDATIONS: If parts required for installation are unavailable locally, contact Edelbrock directly.

• BRACKETS

1. Due to the design and leg configuration on the Edelbrock manifold, the throttle and kick-down bracket on some model vehicles

requires modification to fit. If this condition occurs with your installation, you may purchase the Edelbrock mounting bracket #8030,

#8036, or modify your bracket as shown in Figure 3.

2. The carburetor location has been moved up by 0.7” and forward by 0.125” from the OEM location for maximum performance. If your

throttle cable bracket fastens to the carburetor pad you won’t have a problem. If your bracket fastens to the back of the manifold use

throttle cable extension kit #8012. (To install #8012 properly, depress the throttle pedal fully, open the carburetor to WOT, and then

install the #8012 extension to the carburetor). Failure to do this will prevent your throttle pedal from tripping the transmission sensor at

WOT. This affects transmission kick-down and up-shift points resulting in reduced performance. Older vehicles with solid throttle rods

may need to use throttle rod extension #8010.

3. If using a carburetor with a remote choke, use Edelbrock choke rod #9172 with the OEM choke thermostat.

• GASKETS AND SEALANT CAUTION: Do not use high performance or competition type intake gaskets for street application. Due to material deterioration under street driving conditions, internal leakage of both vacuum and oil may occur. 1. Use only #7201 Edelbrock gasket set, Fel-Pro printoseal, or OE equivalent when installing Edelbrock manifolds for street applications. 2. Apply Edelbrock Gasgacinch sealant, #9300, to both sides of the manifold as well as head surfaces. This procedure ensures a good seal. 3.

GENERAL INSTRUCTIONS FOR INTAKE MANIFOLD REMOVAL AND INSTALLATION The following instructions must be carefully studied and understood before you remove your stock manifold. Failure to follow these instructions may void the warranty. NOTE: Included with your Edelbrock manifold package is a separate manifold instruction sheet. That instruction sheet lists carburetor selection, installation parts, modifications (if needed), and all technical specifications. This must be read carefully.

HOOD CLEARANCE THINGS TO DO BEFORE YOU REMOVE THE STOCK MANIFOLD C B EA D AR W Fig. 2 AIR CLEANER B EA 2-3" D D CLAY CONE AR W CHECKING HOOD CLEARANCE: NOTE: Check hood clearance BEFORE removing stock manifold. 1. Use modeling clay or putty and make five stools, two or three inches high. 2. Position stools on air cleaner at front, rear, each side and on center stud. See Figure 1. 3. Close hood to locked position and re-open. MANIFOLD AND CARBURETOR HEIGHT: 1. Remove the air cleaner. HEIGHT B 2.
PAGE 5
AIR CLEANER: Use stock air cleaners unless changing carburetor. NOTE: If a new or replacement air cleaner is used, there may be inadequate hood clearance. Make sure it performs the same function as stock and meets legal emissions requirements. AUTOMATIC TRANSMISSION CHECK: 1. To assure best performance, economy and emissions, the shift point MUST be checked before and after the manifold change. We suggest this method. From a standing start in drive, PUSH THE THROTTLE WIDE OPEN. Hold in this position.

REMOVING THE STOCK MANIFOLD: 1. Disconnect battery. 2. For ease of installation, keep all parts in some sort of order. WARNING: Do not remove manifold if engine is hot. 3. Drain radiator coolant (drain plug will normally be located on lower right facing engine). NOTE: See individual manifold installation sheet for water draining requirement. Some engines do not require draining, such as Cadillac, 383-440 Chryslers, 351-C and 351-M Fords. 4. Remove gas cap to relieve pressure. Disconnect fuel line and plug.

3. Within a few minutes gaskets and surface will become tacky to the touch. Carefully place gaskets on head surface, aligning ports and bolt holes. 4. With Gasket in place apply a small amount of RTV High Temp silicone sealer around water passages intake manifold side. See Figure 8. Figure 8 5.. With Edelbrock manifolds, you must use RTV High Temp silicone sealer instead of end seal gaskets. Apply a 1/4" thick ribbon of sealant across each end seal surface.

6. Disregard previous mark placed on distributor. 7. Install distributor so that rotor lines up with new mark and points are just open or magnetic trigger wheel aligns with sensor. 8. Final setting to factory specifications is made with a timing light. NOTE: Rotate distributor opposite direction of rotor rotation to advance timing. Rotate with rotor rotation to retard timing. If these instructions are followed carefully, the engine should start and not backfire after the manifold installation.

FOULED PLUGS AND OIL LEAKS: 1. Failure to re-torque manifold. 2. Incorrect manifold gaskets and sealant. 3. Faulty PCV valve or use of incorrect PCV valve. 4. End seal slippage or failure to use enough RTV sealant in place of end seals. AUTOMATIC CHOKE PROBLEMS: Failure to follow instructions completely or clogged exhaust crossover passages. Figure 12 TROUBLESHOOTING: Below is a list of the most common problems experienced after a manifold installation.

Edelbrock replacement manifolds are designed to maintain high vacuum at cruise throttle position and sharp throttle response with minimum throttle opening. Unnecessary demands on the added performance will affect mileage.
