INSTALLATION INSTRUCTIONS

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.

IMPORTANT NOTE: Proper installation is the responsibility of the installer. Improper installation

DESCRIPTION: Edelbrock Performer series intake manifolds are designed for engines operating in the idle to 5500 rpm range. Performer RPM

series intake manifolds are designed for engines operating in the 1500-6500 rpm range. Match Performer or Performer RPM intake manifolds

with recommended carburetors and additional equipment for even greater performance increases.

APPLICATIONS:

INTAKE MANIFOLD REFERENCE APPLICATION

2181

B, C, D, E, F

B, C, D, E, F

Performer RPM 351W: Designed for 1969 and later 351 c.i.d. Ford Windsor V8s with Edelbrock

Performer RPM cylinder heads, modified OEM cylinder heads, or equivalent. No provision for exhaust

heated choke or rear water crossover. Choke block-off plate #8981 included.

7581

A, C, D, F

RPM Air-Gap 351W: Designed for 1969 and later 351 c.i.d. Ford Windsor V8s with Edelbrock

Performer RPM cylinder heads, modified OEM cylinder heads, or equivalent. Features an Air-Gap

design, resulting in a cooler, denser charge for more power. Features a larger cross sectional area

and taller carb flange for compatibility with large displacement 351W based stroker engines. No

provisions for exhaust heated chokes and no exhaust crossover. Will not fit stock hood.

A - Not legal for sale or use on pollution controlled motor vehicles.

B - Engine Swaps: Intended for engines swapped into pre-pollution controlled vehicle.

C - Available in additional finishes, such as polished, black, or EnduraShine. See Catalog for details.

D - Aftermarket 4-bbl carburetors are not compatible with Ford AOD. Performer Series and Thunder Series AVS carbs will work with Ford AOD when

used with Lokar bracket SRK-4000, for more info call (865) 966-2269 or go to www.lokar.com

E - Will fit 1964-1/2 - 1970 Mustangs. Will not fit under stock hood of 1974-1978, or 1979-1995 Mustangs.

F - Will fit early 16 bolt heads when used with Ford 16 bolt intake gasket set. For van installations use Ford “van” intake gasket set.

• EGR SYSTEMS: Edelbrock Performer manifolds equipped with EGR are compatible will exhaust emissions or emissions related stock

components. Non-EGR equipped manifolds 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. Even though manifolds are compatible with EGR systems, this does not mean they

are legal for use on emissions controlled vehicles. Check local laws for legality.

• 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 BRACKETS: Due to the design of Performer manifolds, the throttle and kickdown bracket on some vehicles may require

modification to fit. When using Edelbrock carburetors, use #1491 or 1846 throttle plate kit.

Performer RPM Series Intake Manifolds 1. Due to design, the fuel / air mixture and cylinder charging are very efficient with Performer RPM or RPM Air-Gap manifolds. Generally speaking, the stock jetting for a Performer Series or Thunder Series carburetor will not need changing. Specific applications may show an increase in power by tuning the fuel mixture. 2. Aftermarket distributor curve kits may be used with Performer RPM series manifolds. 3.
