Small Block Chevrolet Engines Holley Contender Manifold

The Holley Dominator II Manifold, 300-36 has been designed for use on small block Chevrolet engines (265-400 C.I.D.). Its low-end torque and usable power range off idle to 7200 RPM makes it ideal for street and street-strip applications.
NOTE: It may be necessary to purchase some of the parts listed below (or the equivalent) in order to properly complete the manifold installation. Determination of equivalency is the responsibility of the consumer, and Holley does not assume that responsibility.
INSTALLATION INSTRUCTIONS:
1. Remove the air cleaner.
2. Prior to removing any vacuum lines, identify the routing of the lines, and also, whether or not the source of vacuum is a “timed (ported) vacuum” source or “direct vacuum” source. (It is helpful to make a schematic sketch of the vacuum line routing). “Timed vacuum” sources and “direct vacuum” sources can be determined as follows:
A. Start the engine and allow it to warm up to operating temperature.
B. With the engine idling, disconnect each vacuum line (one at a time) and note if there is manifold vacuum. If there is vacuum, the source is a “direct vacuum” source. If there is no vacuum, the source is probably “timed”. Check by slowly opening the throttle to approximately 2000 RPM. You should now feel vacuum from the “timed” source. Mark and remove the vacuum lines.
3. Disconnect the ground cable from the battery.
4. Drain the radiator. (It may be necessary to remove the bottom radiator hose, if there is no drain plug in the radiator). WARNING: Be careful of hot water and steam if the engine is still warm.
5. Disconnect the throttle linkage, transmission kickdown linkage, and choke from the carburetor.
6. Remove the gas cap to relieve pressure from the fuel system. Disconnect and plug the fuel line at the carburetor.
7. Disconnect the power brake line and remove the carburetor.
8. Tag and remove the coil wires and bracket.
9. Remove the top alternator bracket and rear air conditioning bracket. It may be necessary to remove the air pump hose from the left air injection manifold for clearance.
10. Remove the heater hose and top radiator hose complete with the thermostat housing. Remove the thermostat.
