•
EXHAUST EMISSIONS SYSTEMS:
Edelbrock EGR-equipped Performer T.B.I. manifolds are intended as a direct replacement for
their O.E.M. counterparts. All exhaust emissions or emissions-related stock components will be retained and functional.
•
THROTTLE BODY INJECTORS:
Use only OEM-type throttle body fuel injectors and base gasket. Label all vacuum lines removed
for re-attachment to the T.B.I. The use of aftermarket throttle body injection units is not recommended.
•
BRACKETS:
The throttle cable bracket from a 1991 454SS truck is required. Use Edelbrock #8019 or GM #10111685. On some
applications, the end of the bracket will need to be cut off. Use a hacksaw to remove about two inches from the end where the
cable housing mounts.
•
CRUISE CONTROL:
If the factory cruise control rod will not fit, use GM part #14009160.
•
EGR VALVE:
Manifold will accept OEM EGR valve. If a replacement valve is needed, use GM #17090051.
•
WATER JACKET:
Do not use the OEM water jacket plate between the injector base and the Performer T.B.I. manifold, as this
water cavity is already cast into the manifold. Use the OEM formed hose from the front water outlet (just below the T.B.I.) to the
front water passage, and the original fitting in the front water passage. It is important to use the correct mixture of anti-freeze
and water in your cooling system, as water only will quickly corrode the intake manifold.
•
GASKETS AND SEALANT:
Do not use high-performance or competition-type intake gaskets for street applications. Due to
material deterioration under street conditions, internal leakage of both vacuum and oil may occur.
•
FIRING ORDER AND CYLINDER NUMBERING:
For cylinder numbering and firing order, see Figure 2.
•
FINAL TUNING:
NOTE:
Local emission laws must be checked for legality of injector or ignition changes.
