How To Set Timing On Sbc With Hei? Do instead of advancing your timing as the throttle in opened it actually retards your timing as the throttle is opened. That is why your suppose to hook the.
Setting timing on an SBC with HEI can be a fairly simple task, particularly if you have the right tools and knowledge. In this article, I will explain how to properly set the timing on an SBC with HEI, and provide some tips to help you get the job done quickly and safely.
Before you start, make sure to have the following tools on hand: a timing light, a screwdriver, a ratchet and socket set, a ruler or measuring tape, and a vacuum gauge. Additionally, it is important to familiarize yourself with the engine’s firing order, as this will be needed to properly set the timing.
The first step is to make sure the engine is off, and the ignition is in the off position. Next, disconnect the battery cables. Then, take the distributor cap off, and remove the spark plug wires from the distributor. Once this is done, you can begin setting the timing.
To set the timing, you will need to rotate the distributor until the timing mark lines up with the timing pointer. You can use the ruler or measuring tape to make sure the timing mark is in the correct position. You will also need to make sure the rotor is pointing to the correct cylinder. To do this, you can use the vacuum gauge to check the vacuum advance. Once you have verified the timing and the vacuum advance, you can replace the distributor cap and spark plug wires. Then, reconnect the battery cables and start the engine.
Once the engine is running, you will need to adjust the timing with the timing light. This is done by connecting the timing light to the number one spark plug wire and the battery. Then, adjust the timing until it is in the specified range. Make sure to double-check the timing after adjusting it, and make any necessary adjustments.
Finally, you will need to check the idle speed. This is done by checking the RPM of the engine when it is in the idle position. Make sure to adjust the idle speed as necessary to ensure it meets the manufacturer’s specifications.
In conclusion, setting the timing on an SBC with HEI is a fairly easy and straightforward task. However, it is important to make sure you have the right tools and knowledge before attempting this task. Additionally, make sure to double-check the timing and the idle speed after you have adjusted it, and make any necessary adjustments. Following these steps will help ensure that your engine is running properly and efficiently.
