• THROTTLE BRACKETS: The throttle and kickdown bracket on some vehicles may require
modification to fit. When using Edelbrock carburetors, use #1493 or 1847 throttle plate kit
to line up the stock throttle bracket to the Edelbrock carburetor throttle lever.
• CARBURETOR PLATES AND GASKETS: Installation of Edelbrock square-bore based
carburetor requires Edelbrock square-bore carburetor adapter #2732 (supplied). Use the
manufacture supplied carburetor gasket on top of the #2732 kit
(See Figure 1).
• SPECIAL INSTRUCTIONS: Charcoal purge canister and PCV hose on later model vehicles
connects to the front of the OEM intake manifold. The charcoal purge canister vacuum
hose will have to be connected with the 3/8" PCV hose. The PCV hose will have to be
rerouted to the side of the Holley carburetor.
(See Figure 2).
NOTE: Pipe fittings on the front of the intake are not for coolant.
• PREP AND TUNING FOR POWER:
1.
Due to design, the fuel / air mixture and cylinder charging is very efficient with
Performer 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. Performer manifolds deliver excellent driveability and power
utilizing the factory OEM distributor settings.
Specific
applications may benefit from resetting the initial timing + or -
2° from the factory specifications. Aftermarket distributor curve
kits may be used with Performer series intake manifolds.
4. Installation of aftermarket headers, camshafts or both with an
Edelbrock Performer RPM series manifold may lean carburetor
calibration. Should this condition occur, recalibrate with a richer
jet.
• CAMSHAFT AND HEADERS: Performer Series manifolds are
compatible with aftermarket camshafts and headers designed to
work in the idle-5500 rpm range. Edelbrock has developed a dyno-
matched, street-proven camshaft, Performer-Plus #2172, which is
ground specifically for use with the Performer 400 intake manifold.
Header primary tube diameter should be 1-5/8".
1. 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. Apply Edelbrock Gasgacinch sealant P/N 9300 to both
cylinder head flanges and to the cylinder head side of the
gaskets, allow to air dry, and attach the intake gaskets.
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.
5. Install the intake manifold and hold-down bolts. Torque
all of the manifold bolts in two steps by the sequence
shown in Figure 3 to 25 ft/lbs. For ease of installation, we
recommend Intake Manifold Bolt Kit #8574.
