Caution
This engine assembly needs to be filled with oil and primed. You should add the specified oil (see start-up instructions) to your
new engine. Check the engine oil level on the dipstick and add accordingly.
Start-up and Break-in Procedures
1.
After installing the engine, ensure the crankcase has been filled with 5W30 motor oil (non-synthetic) to the recommended
oil fill level on the dipstick. Also check and fill as required any other necessary fluids such as coolant, power steering fluid,
etc.
2. The engine should be primed with oil prior to starting. Follow the instructions enclosed with the tool. To prime the engine,
first remove the distributor to allow access to the oil pump drive shaft. Note the position of the distributor before removal.
Install the oil priming tool. Using a 1/2" dill motor, rotate the engine oil priming tool clockwise for three minutes. While you
are priming the engine, have someone else rotate the crankshaft clockwise to supply oil throughout the engine and to all
the bearing surfaces before the engine is initially started. This is the sure way to get oil to the bearings before you start the
engine for the first time. Also, prime the engine if it sits for extended periods of time. Reinstall the distributor in the same
orientation as it was removed.
3.
Safety first. If the vehicle is on the ground, be sure the emergency brake is set, the wheels are chocked and the car cannot
fall into gear. Verify everything is installed properly and nothing was missed.
4. Start the engine and adjust the initial timing. If using the HEI distributor P/N 93440806, set the ignition timing to 4º before
top dead center (BTDC) at 650 rpm with the vacuum advance line to the distributor disconnected and plugged. This
setting will produce 26º of total advance at wide-open throttle (WOT) when using the HEI distributor P/N 93440806. 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. Rotate the distributor counterclockwise to advance the timing.
Rotate the distributor clockwise to retard the timing.
