3. Within a few minutes gaskets and surface will become tacky to the
touch. Carefully place gaskets on head surface, aligning ports and
bolt holes.
4. With Gasket in place apply a small amount of RTV High Temp
silicone sealer around water passages intake manifold side. See
Figure 8.
5.. With Edelbrock manifolds, you must use RTV High Temp silicone
sealer instead of end seal gaskets. Apply a 1/4" thick ribbon of
sealant across each end seal surface. Some installation require
02 sensor safe silicone See Figure 9.
MANIFOLD INSTALLATION:
1. Carefully position manifold on engine, centering bolt holes with
bolt holes in head.
NOTE: On some Ford and Pontiac manifolds, study manifold
instruction sheet for special instructions.
2. Refer to manifold instruction sheet for placement of any special
bolts furnished with your manifold.
3. Apply RTV silicone or Teflon tape to bolt threads, where exposed to
water, oil or engine vacuum..
4. Start all bolts by hand. Refer to individual manifold instructions for
torque sequence.
CARBURETOR INSTALLATION:
CAUTION: Use only recommended carburetors listed on manifold
instruction sheet. You MUST use a new base gasket. For non-OEM
carburetor, install according to manufacturer’s instructions. Use
gaskets furnished with carburetor.
1. Connect all fuel lines, linkage and throttle springs.
2. Connect all vacuum lines. Refer to your drawing or tags for
correct placement.
WIRING
Connect all electrical wiring as per drawings or tags.
2. Install thermostat with proper orientation. Apply Edelbrock RTV
silicone on manifold surface using a new gasket and place it in
position aligning holes. Apply RTV silicone to water neck surface
and bolt threads. Position water neck. Start bolts by hand and
tighten.
3. Make sure radiator drain is closed. Replace coolant.
4. Re-connect battery.
INSTALL IGNITION:
1. Manifold must be in place and torqued to specifications.
2. Install distributor with rotor pointing to your mark on the housing
and the vacuum can lined up with your mark on the firewall or
valve cover. See Figure 10.
3. Make sure the distributor is all the way down and ignition shaft is
fully engaged in oil pump drive.
4. Rotate distributor until point opening or magnetic trigger wheel
alignment is the same as when you removed the ignition.
5. Install hold down clamp and tighten to hold in place.
6. Final setting to specifications must be made with a timing light.
RE-TIMING ENGINE:
NOTE: If for some reason engine was rotated, the engine must
be re-timed. Use the following procedure for re-timing the engine.
1. Remove spark plug from No. 1 cylinder. See individual manifold
instruction sheet for No. 1 cylinder.
2. Remove coil wire from distributor and ground it.
3. THIS STEP REQUIRES TWO PEOPLE OR A
REMOTE STARTER SWITCH. One person rotates engine
by slowly bumping starter. One person holds his finger over the
No. 1 plug hole until compression is felt.
4. Continue to bump starter until timing mark on the crankshaft
pulley shows approximately 5 degrees before top dead center.
5. See Figure 10 for correct positioning of rotor and ignition on No. 1
cylinder.

THERMOSTAT:
1. To ensure proper function of your thermostat, place it in a pan of
boiling water. It should open quickly to the wide open position. If
questionable, replace it with one for the correct year and model of
your vehicle.
