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, GM part number 12368084. 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. Set the ignition timing to 10? before top dead center (BTDC) at 650 rpm with the vacuum advance line to the distributor disconnected and plugged. This setting will produce 32? 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. Rotate the distributor counterclockwise to advance the timing. Rotate the distributor clockwise to retard the timing.

5. When possible, you should always allow the engine to warm up prior to driving. It is a good practice to allow the oil sump and water temperature to reach 180?F before towing heavy loads or performing hard acceleration runs.

6. Once the engine is warm, Double check the total advance timing is 32? at 4000 RPM if using the deluxe engine configuration.

7. The engine should be driven at varying loads and conditions for the first 30 miles or one hour without wide open throttle (WOT) or sustained high RPM accelerations.

8. Run five or six medium throttle (50%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.

9. Run two or three hard throttle (WOT 100%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.

10. Change the oil and filter. Replace with 5W30 motor oil (not synthetic) and a PF454 AC Delco oil filter. Inspect the oil and the oil filter for any foreign particles to ensure that the engine is functioning properly.

11. Drive the next 500 miles under normal conditions or 12 to 15 engine hours. Do not run the engine at its maximum rated engine speed. Also, do not expose the engine to extended periods of high load.

12. Change the oil and filter. Again, inspect the oil and oil filter for any foreign particles to ensure that the engine is functioning properly.

13. Do not use synthetic oil for break-in. It would be suitable to use synthetic motor oil after the second recommended oil change and mileage accumulation. In colder regions, a lower viscosity oil may be required for better flow characteristics.

ZZ502 Component Information Ignition System The HEI distributor (GM Part Number 93440806) included with the ZZ502 deluxe engine 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 distributor supplied with the ZZ502 deluxe engine has a hardened drive gear that is compatible with a steel camshaft. Use of a non-hardened distributor gear will result in excessive wear.

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 GM Part Number 12167658, which includes connectors and wires for the HEI's tachometer and 12 volt terminals.

Water Pump The ZZ502 deluxe engine comes with an aluminum, short style water pump, GM Part Number 14058915. The pump included with this kit has a standard rotation impeller that is used with conventional accessory drives. Some serpentine belt systems require a water pump with a reverse-rotation impeller. In these instances, install a water pump specified for the original application.

Timing Information Set initial spark timing at 10? before top dead center (BTDC) at 650 rpm with the vacuum advance line to the distributor disconnected and plugged. This setting will produce 32? 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. The HEI distributor supplied with the ZZ502 deluxe engine has mechanical centrifugal spark advance with the following curves:

Mechanical Advance:

RPM

Advance

1100

0.0?

1600

12.0?

2400

16.0?

4600

Carburetor The carburetor included with the ZZ502 deluxe engine is a Holley 4-barrel Model 4150 dual feed fuel inlet, vacuum secondary carburetor. This carburetor features center hung float bowls, electric choke, power valve blow-out protection, and a secondary power valve. It has the correct calibration for ZZ502 crate engines. For more information and carburetor set up instructions, see the specific carburetor instruction sheet or visit .

Air Cleaner The ZZ502 deluxe engine does not include an air cleaner assembly. GM Part Number 12342080, is a chrome, 14 inch, low profile air cleaner assembly with CHEVROLET on its cover. This part number is supplied with a 3 inch tall air cleaner element, GM Part Number 6421746. A taller 4 inch air cleaner element is available as GM Part Number 8997189.
