Run the engine between 2,000 and 2,500 RPMs, with no-load on the engine for the first 30 minutes. |

After the engine has been running for 30 minutes, set the ignition timing (see install ignition section for timing specifications). |

| 9. |
Run a couple hard-throttle accelerations up to about 5000 RPMs (55 to 60 MPH), then let off in gear and coast back down to 20 MPH. |
| 10. |
Change the oil and filter with 10W30SG oil and appropriate ACDelco oil filter. |
