In the vast majority of cases, the manifold may be installed without modifications, if further port matching is required, material removal should be blended up at least two inches into the runner. Since the casting lines between the runners and the plenum floor are located entirely outside of the runner entries, an ideal runner approach radius is insured as cast.
Note: It may be necessary to purchase some of the parts listed (or the equivalent) in order to properly complete the manifold installation. Also, before moving the distributor, set the rotor to the number one cylinder.
Note: To reduce chances of engine contamination by dirt or other foreign material, it is advisable to clean the engine exterior before starting the manifolds change.
After removing the distributor and existing intake manifold, clean the gasket surfaces prior to installing the Small Block Pro Ram system. It is recommended at this point to use the Green Lee Punches or a hole saw to put a 1 5/8” hole in the fire wall to accommodate the Main Wire Harness. (Remember to cover engine completely when drilling through the firewall) Once the gasket surface has been cleaned, apply a fine bead of silicone on the bottom sides of the replacement intake gaskets and place on the heads.
Next, place a 1/4” bead of silicone on both ends of the engine block. With all the intake gaskets in place, carefully place the assembled Small Block Single Plane Multi Point System onto the engine. Be sure that the gaskets are still aligned with the bolt holes and start to thread the intake bolts into the engine heads. Torque the intake bolts first to 20 LB/ft. then to 30 LB/ft. Next install the distributor making sure that the rotor is aligned properly with the No.1 cylinder cap tower location.
The next step is to route the vacuum lines. The following items need to be referenced to manifold vacuum:
1) Map sensor 2) Pressure regulator 3) Power brake booster 4) PCV 5) Transmission kick-down Note: Never splice the Map Sensor or Pressure Regulator vacuum lines.
MOUNTING THE ECM
The ECM comes with four mounting holes designed for a #8 screw. The ECM should be mounted behind the passengers kick panel on the floor. If your kick panel has an air vent incorporated into it, DO NOT mount the ECM here. This enclosure is not waterproof and therefore needs a mounting place free of moisture. The alternate location is in the dash board area behind the glove box; you can also mount the ECM in the engine compartment although it is not recommended since it is only moisture resistant and not water proof. .
MAIN WIRE HARNESS ROUTING AND CONNECTIONS BEFORE PROCEEDING DISCONNECT BOTH BATTERY TERMINALS FROM THE BATTERY.
The System contains two (2) Wire Harnesses. A Main Wire Harness (this will be referenced as the MWH in the following instructions) and an Injector Wire Harness.
The harness can be routed and connected as follows: Begin by connecting the MWH’s connectors to the ECM. Then route MWH leg through the firewall hole. Continue pulling the harness leg through the firewall until the rubber grommet seat the firewall.
Make sure to connect the +12 V switch (PINK) to the switched IGN accessory in the fuse box. The switched ignition accessory must maintain 12 volts during cranking. Connect + 12 V (3/8” ring terminal), and battery ground (3/8” ring terminal) connectors directly to battery. (Do not connect to back of alternator) Then connect all sensors and IAC (connectors are labeled). Finally connecting the fuel pump; (Refer to fuel pump mounting) if you need to lengthen the red/black 12 volt+ wire to the fuel pump, be sure to use at least a 14-gauge wire.
