• Gaskets:
1. Use only a high quality intake manifold gasket set such as Edelbrock #7280 or equivalent.
2. Do not use the plastic locating buttons supplied with some gasket sets, as Edelbrock manifolds are not machined to
accept these buttons.
3. Apply Edelbrock Gasgacinch sealant, Catalog #9300, to the cylinder head flanges and the back of the gasket. Allow to
air dry before pressing in place. This procedure ensures a good seal.
•
Manifold Torque:
1. Use Edelbrock Intake Manifold Bolt Kit, Catalog #8559.
2. After setting manifold on engine and starting all bolts by hand, install water pump bolt and tighten so manifold seals
against water pump.
CAUTION:
It may be necessary to shorter water pump bolt if it bottoms out before seating.
3. Then torque all bolts circled in Figure 1 to 25 ft./lbs.
See Figure 1 for proper sequence.
•
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 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.
❑
Activate the fuel pump and fully check the system for any leaks prior to starting the engine.
