Additional Parts That May Be Needed
Harmonic Damper:
The 350/265 HP engine does not include a harmonic damper. It does include two timing tabs to use either a 6 3/4" or 8" damper. Part Number for the 6 3/4"
damper is 12551537 and for the 8" is 19301706. Use damper retaining bolt P/N 09440024 and washer P/N 14001829.
Intake Manifold:
The 350/265 HP Base engine does not come with an intake manifold. Recommended intake manifold is 10185063.
Water Pump:
The 350/265 HP Base engine does not come with a water pump. Recommended water pump P/N is 88894341.
Ignition System:
Recommended distributor is the HEI (High Energy Ignition) distributor P/N 93440806. This distributor is a self-contained ignition system that includes a magnetic
pickup, a module, a coil, a rotor, and a cap. The HEI's large diameter cap minimizes arcing and cross-firing between adjacent spark plug terminals. The cap's male
terminals provide a reliable, positive connection for the spark plug leads. However, the HEI's large diameter cap may interfere with other underhood components
in vehicles not originally equipped with HEI ignition systems. Check for adequate clearance before installation.
The HEI system requires a 12 volt power supply for proper operation. The HEI ignition system should be connected directly to the battery with 10 or 12 gauge
wire through a high quality ignition switch. If you are installing an HEI ignition in an early-model vehicle originally equipped with a point-type ignition, be sure to
remove or bypass the resistor in the wiring harness to ensure the HEI receives 12 volts continuously. Use distributor connector package P/N 12167658, which
includes connectors and wires for the HEI's tachometer and 12 volt terminals.
Set spark timing at 32º before top dead center (BTDC) at 3000 RPM with the vacuum advance line to the distributor disconnected and plugged. This setting will
produce 32º of total advance at wide open throttle (WOT). The HEI vacuum advance canister should remain disconnected. This engine is designed to operate
using only the internal centrifugal advance to achieve the correct timing curve.
Flywheel / Flexplate:
Like all small block V-8 engines produced before 1986, the 350/265 HP engine has a 3.58" diameter flywheel flange bolt pattern and uses a 2 piece rear main oil
seal design. Small block V-8 engines produced from 1958 through 1985 had a 3.58" diameter flywheel flange bolt pattern. The 350/265 HP engine must use a
zero balance flywheel/flexplate (no additional weight) for proper balance. The 350/265 HP engine does not include a flywheel or flexplate. Flywheels and
flexplates are available from the chart below.
