• EGR SYSTEMS: Edelbrock EGR (Exhaust Gas Recirculation) equipped Performer manifolds are intended as a direct functionally identical
replacement for their OEM counterparts. All exhaust emissions or emissions-related stock components are intended to be retained and functional.
Check local laws for requirements. EGR systems are used on most 1972 and later model vehicles. Check local laws for requirements.
• THROTTLE BODY RECOMMENDATIONS: Use only the OEM-type, small-block throttle body injection unit (1-11/16” throttle bores). The use of
GM or aftermarket 2” throttle body injection units is not recommended.
• GASKETS: Do not use competition-style intake gaskets for this manifold in street/strip or endurance applications. Due to material deterioration
over time, internal leakage of vacuum, oil, and coolant may occur.

• POWER PACKAGE OPTIONS: The Edelbrock Performer TBI intake manifold is part of a total Power Package Parts System that can be completed
with the use of dyno-matched Performer-Plus camshaft #3702, Performer Centerbolt cylinder heads #60859 (sold individually), and related parts
designed to give you maximum results. Please refer to the Power Package Guide in the Edelbrock Catalog for further details.
• AFTERMARKET CAMSHAFTS AND HEADERS: Use only parts that are compatible with computer controlled engines, such as Edelbrock camshaft
#3702, and Edelbrock Tubular Exhaust Systems. Do not use header systems which are not tested for compatibility with computer-controlled TBI
systems. Those headers may not position the O2 sensor in the correct location, causing improper operation of the fuel injection system.
• SPECIAL NOTE: Some applications wil require an extra 3/8-16 threaded bolt hole to attach factory bracketry. If needed, locate the dimple in the
manifold casting
(See Figure 1) and drill a 5/16” hole 1-1/8” deep. Tap this hole with a 3/8-16 thread tap, 1” deep.
