305-400 C.I.D. Chevrolet V8 Street Tunnel RAM Intake Manifold Installation Instrucitons

February 26th, 2011 · No Comments

The Street Tunnel Ram manifold is designed for use on 305-400 c.i.d. small-block Chevrolet V8 engines. It is intended for small-block Chevrolets operating below 7500 rpm where low-end torque is not a prime factor. Especially suited to engines using slightly modified cylinder heads (9.5:1 or more compression is advised). Use the recommended carburetors only. Top has vacuum outlet for power brakes Manifold will accept forward or sideways mounted carburetors. Distance from carburetor center to center is 8.875″. GM H.E.I. ignition will not clear manifold. Will not fit 1987 and later cast iron cylinder heads. Original alternator bracket may not fit; use aftermarket universal brackets as required.
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 ž” 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 hold-down bolts (We offer an Intake Manifold Bolt Kit #8504 that includes small-head silver Cadmium-plated bolts and matching hardened washers). Apply a small amount of RTV silicone to the threads of the eight inner bolts (1, 2, 3, 4, 5, 7, 9, & 11) (See Figure 1). This will prevent oil weepage, as generally these are not blind holes in the cylinder head.
6. Torque all of the manifold bolts in two steps by the sequence shown in Figure 1 to 25 ft/lbs.
