INSTALLATION PROCEDURE
•
INJECTOR WARNING:
It is important to select the appropriate electronic injectors for optimum performance. The injectors must not only
match the fuel demands of an engine, but they must also meet the electronic commands of the engine control unit (ECU). Once injectors and
an ECU is determined, make sure that when installing the injectors onto the manifold, that the o-rings of the injectors create a complete seal
to prevent any air or fuel from leaking out. The same precaution should be applied when assembling the injectors to the fuel rails.
•
POWER OPTIONS:
Although this manifold will work with ported factory cast iron heads, we highly recommend the use of our #60979 or
60989 Performer RPM E-Tec cylinder heads. These heads offer higher airflow levels with minimum preparation required. See our catalog
for details. We also recommend port matching the intake manifold .020” smaller than the gasket, or cylinder head, whichever is smaller.
•
INTAKE MANIFOLD INSTALLATION:
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 1 to 11
ft/lbs. While tightening the intake manifold bolts, the distributor
should be installed in its proper position. Care should be taken to
make sure that the distributor is centered in the hole in the intake
manifold and that it can be freely removed and reinstalled after the
intake manifold bolts are tightened.
•
FUEL RAIL INSTALLATION (29136 ONLY):
1. Select the appropriate fuel rail brackets (Tall for injectors with 2.65” o-ring spacing, or short for 1.5” o-ring spacing). Attach the four
fuel rail brackets to the intake manifold using the four 1/4-20 x 1/2” socket head bolts and four of the 1/4” flat washers.
2. Press your injectors into the intake manifold using a small amount (one or two drops is sufficient) of silicone based o-ring lubricant
(such as brake cylinder assembly lube) on the o-rings.
3. Press the fuel rails over the fuel injectors until fully seated.
4. Using a 1/4” flat washer on each side of the fuel rails at each of the four bolt holes, secure the fuel rails to the brackets using the
1/4-20 x 1-1/2” hex head bolts and the 1/4-20 Nyloc hex nuts.
5. Make sure the injectors can still rotate freely in their bores after the fuel rails are installed.
•
FINAL CHECKS:
After assembling the injectors, fuel rails, support brackets, throttle body, spacer (if needed), gaskets, and air cleaner, check
the following:
❑
Have an assistant depress and release the gas pedal. Check for full open throttle at the throttle body. Check for any possible
interference of the throttle with other components. Make sure the throttle can return to closed without binding.
❑
Check the fit of each injector. They should be able to rotate freely. The O-rings should be fully inside their respective bores.
❑
If applicable, make sure there will be enough hood clearance after the air cleaner has been installed.
❑
Activate the fuel pump and fully check the system for any leaks prior to starting the engine.
