DESCRIPTION: The Edelbrock Performer RPM Air-Gap LT1/LT4 intake manifolds feature a tunnel-ram design that offers performance increases in the 1500-6500 RPM range. The Air-Gap design separates the runners from the hot engine oil, resulting in a cooler, denser charge for more power. Manifold #7107 is designed to fit 1992-1997 GM LT1 engines, and is matched to our Performer LT1 cylinder heads #61909. If using OEM cylinder heads, gasket matching of the cylinder head intake ports is recommended for optimum performance. The #7109 is designed for 1994-1995 GM LT4 engines. #7109 will also fit 1992-1997 LT1 engines that have installed LT4 style cylinder heads. The #7109 is matched to our Performer LT4 cylinder heads, #61939. It may also be used with our Performer LT1 cylinder heads #61909, with minor port matching of the cylinder head recommended for optimum performance. With OEM LT4 cylinder head applications, such as 1994-1995 LT4 engines, or 1992-1997 LT1 engines with LT4 heads, port matching of the cylinder head is useful for optimum flow Both manifolds accept stock or aftermarket fuel rails and include an OEM style throttle body pad that will accept oversized throttle bodies up to 58mm.

• 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.

• EGR SYSTEMS: The Performer RPM Air-Gap LT1/LT4 intake 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.

• THROTTLE BODY RECOMMENDATIONS: Performer RPM Air-Gap LT1/LT4 intake manifolds feature a throttle body pad that will accept OEM and oversized throttle bodies up to 58mm. For optimum performance, match with Edelbrock throttle bodies. Edelbrock offers two throttle bodies for 1994-1997 LT1 applications; a 52mm (#3809) and a 58mm (#3810).

• THROTTLE CABLE & ACCESSORY BRACKETS: Manifolds will accept factory throttle cable and accessory brackets.

• 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.

INSTALLATION PROCEDURE

• INSTALLATION:

1. Transfer all factory hardware and emissions equipment to the Edelbrock intake manifold.

2. 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. Attach the intake gaskets to the cylinder head. Make sure the guide pins on the gaskest are aligned with the holes in the intake flanges

of the cylinder heads.

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. Set manifold assembly on engine.

5. Install the intake manifold hold-down bolts. Torque all of the manifold bolts in two steps by the sequence shown in Figure 1 to 25 ft/lbs.

Torque Bolts to 25 ft/lbs.; Firing Order: 1-8-4-3-6-5-7-2

• TUNING FOR POWER:

1. Aftermarket tuning may be used with this intake manifold.

3. Use modified or high performance cylinder heads such as our Performer LT1 or Performer LT4.

4. Installation of aftermarket headers, camshafts or both may require ECU tuning, and may affect emissions.

• CAMSHAFT AND HEADERS: Performer RPM Air-Gap manifolds are compatible with aftermarket camshafts and headers. Header primary tube diameter should be 1-5/8” to 1-3.4” depending on the specific engine combination. Edelbrock has developed a camshaft for use with this intake manifold on 1992-1997 LT1 engines; Performer RPM #2108 (Will also fit LT4). Please check the catalog or website for rpm and application guidelines.
