Edelbrock 7111 Instructions Manual

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, 8am-12:30 and 1:30-5pm PST, weekdays.
• 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 330-403 is a new generation manifold for 330, 350, and 403 c.i.d. small-block
Oldsmobile engines. It may also be used on 1980-1/2—'85 307 c.i.d. Oldsmobile engines with 5A cylinder heads (casting #3317).
Will not fit 1986 and newer 307 V8s with roller cams and swirl port heads. Port flange has extra material above the runner to allow
for use with 455 heads. The Performer RPM 330-403 is a high-rise, two-plane design, engineered for a horsepower peak in the 6000-
6500 rpm range with a broader torque curve than single-plane manifolds in the lower rpm ranges. Recommended for high-perfor-
mance street, strip and marine applications. The manifold accepts late model water neck, air conditioning, alternator and H.E.I. igni-
tion systems. Use the recommended electric or manual choke carburetors only. NOTE: Carb mount pad is two inches taller than most
stock manifolds, requiring hood clearance check. Will not fit Toronado or Trans-Am without hood modifications.
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 #7112, springs, chain set, carburetors and related parts specifically designed to
give you maximum results.
• CARBURETOR RECOMMENDATIONS:
If parts required for installation are unavailable locally, contact Edelbrock directly.
A-Carburetor will work with non-EGR (Exhaust Gas Recirculation) or pre-emission control system.
F-Use carb-to-manifold base gasket same year/model as vehicle, unless base gasket supplied with carb.
H-Carburetor has provision for evaporative canister.
I-Carburetor has no provision for evaporative canister.
K-Carburetor requires #8008 or #8024 stud, nut and washer kit. Determine length needed before installation.
O-Carburetor has manual choke only.
Note: If electric choke is desired for Edelbrock carburetor #1407, use Electric Choke Kit #1478.
*-Use of EGR-type Quadrajet not recommended; conversion to electric choke required.
• GASKETS AND SEALANT
1. Use only Fel-Pro Valley Pan gasket #MS96027 or OEM equivalent when installing Edelbrock manifolds for street applications.
Mondello Performance Products (1103 Paso Robles St., Paso Robles, CA 93446, phone (805) 237-8808) offers heavy-duty intake
gaskets which are recommended for high-performance applications. Use IG-490 with 350/403 cylinder heads, and IG-500 with 455
cylinder heads. M.P.P. also offers a bolt-in Valley Tray to reduce manifold temperature, part number VT-580.
2. Apply Edelbrock Gasgacinch sealant, #9300, to both sides of the manifold as well as head surfaces. This procedure ensures a good
seal.
3. Eliminate the end seal gaskets. Use RTV Silicone sealant instead. Apply a bead of sealant approximately 1/4" high across the block
end seal surface, overlapping the intake gasket at the four corners. This method eliminates end seal slippage and deterioration.
