Accel DFI Pro RAM Chevy Installation Instructions

Read and follow instructions before, during and after installation to preserve warranty. Also disconnect battery leads and drain engine coolant prior to manifold installation. 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.
