How to choose the right cam for 5.3 Vortec?

There are a few things to consider when choosing the right cam for your 5.3 Vortec. First, you need to decide what type of performance you are looking for. Are you looking for more power, better fuel economy, or both?

Second, you need to know what type of heads and intake you have. If you have aftermarket heads and an aftermarket intake, you will need to choose a different cam than if you had stock heads and an aftermarket intake.

Third, you need to know what type of transmission you have. If you have an automatic transmission, you will need a different cam than if you have a manual transmission. Finally, you need to know what octane fuel you will be using. The higher the octane, the more aggressive the cam can be.

If you are looking for more power, you will want a cam with more lift and duration. The lift is how high the valves open and the duration is how long they stay open. More lift and duration will allow more air and fuel to enter the engine, which will result in more power.

However, it will also result in less fuel economy. If you are looking for better fuel economy, you will want a cam with less lift and duration. This will allow less air and fuel to enter the engine, which will result in better fuel economy. However, it will also result in less power.

The type of heads and intake you have will also affect the type of cam you need. If you have aftermarket heads and an aftermarket intake, you will need a different cam than if you had stock heads and an aftermarket intake. The reason for this is that the aftermarket heads and intake will flow more air and fuel than the stock heads and intake. Therefore, you will need a cam with more lift and duration to take advantage of the airflow. If you have stock heads and an aftermarket intake, you can use a cam with less lift and duration because the airflow will not be as great.

The type of transmission you have will also affect the type of cam you need. If you have an automatic transmission, you will need a different cam than if you have a manual transmission. The reason for this is that the automatic transmission will shift gears differently than the manual transmission. Therefore, you will need a cam with more lift and duration to take advantage of the shifting. If you have a manual transmission, you can use a cam with less lift and duration because the shifting will not be as great.

The octane of the fuel you use will also affect the type of cam you need. The higher the octane, the more aggressive the cam can be. However, it will also result in less fuel economy. If you are looking for better fuel economy, you will want a cam with less lift and duration. This will allow less air and fuel to enter the engine, which will result in better fuel economy. However, it will also result in less power.

Installing a cam for 5.3 Vortec engines

You will need a few tools, including a drill, to make the installation go smoothly.

  1. Begin by disconnecting the negative battery terminal. This will ensure that you don’t accidentally short out any of the electrical components while you’re working.
  2. Next, remove the old distributor cap and spark plug wires. If your engine is still using point-type ignition, you’ll also need to remove the points and condenser.
  3. Unscrew and remove the oil fill tube and dipstick from the valve cover. This will give you more room to work with when it comes time to install the new camshaft.
  4. Using a socket wrench, unscrew and remove the four bolts that hold the timing chain cover in place. Be careful not to lose any of the gaskets or seals that may be attached to the cover.
  5. With the timing chain cover removed, you should now have access to the camshaft and gears. Using a wrench or socket, remove the old camshaft and discard it.
  6. Take your new camshaft and lubricate it with engine oil. This will help reduce friction when you install it.
  7. Carefully position the new camshaft into place, being sure that the lobes are pointing in the correct direction.
  8. Once the camshaft is in position, start threading in the bolts that will hold it in place. Be sure to use a torque wrench to tighten the bolts to the correct specification.
  9. Reattach the timing chain cover, being careful not to damage any of the gaskets or seals.
  10. Screw the oil fill tube and dipstick back into place, and then reconnect the negative battery terminal.
  11. Start up the engine and let it idle for a few minutes. Check for any oil leaks and make sure that all of the electrical components are working properly. If everything looks good, you’ve successfully installed your new camshaft!

A Stage 3 Cam

 

A stage 3 cam is an aftermarket performance camshaft that is designed to deliver significantly more power than a stock or Stage 2 cam. These cams typically have larger lift and duration numbers than their milder counterparts, and are often noisy and not emissions-friendly. Many Stage 3 cams will require other modifications like headers, higher-flow cylinder heads, and increased compression in order to make the most power possible. While a Stage 3 cam can turn your daily driver into a real beast on the street or track, it can also make it difficult to drive in traffic or around town. Think carefully about how you plan to use your car before selecting a Stage 3 camshaft.

Why camshaft numbers are important .

 

When it comes to engines, the camshaft is a vital component. It helps open and close the valves in order to allow air and fuel into the cylinders and exhaust gases out. In other words, the camshaft plays a big role in the breathing of an engine.

 

This crucial component is identified by its number. The camshaft number helps determine how big or small the intake and exhaust valves are. It also affects how early or late they open and close in relation to the piston’s position. All of this is important because it affects an engine’s performance, power, and efficiency.

 

In short, camshaft numbers are important because they help identify an engine’s characteristics. This information is essential for those who want to get the most out of their engine.

The camshaft number can be broken down into four main parts:

– The base circle diameter

– The lobe centerline angle

– The valve lift

– The duration of each of these parts affects the performance of an engine in a different way.

Let’s take a closer look at each one. The base circle diameter is the measurement from the tip of the lobe to the center of the shaft. It’s important because it dictates how big the valves can be. A larger base circle means bigger valves and vice versa. The lobe centerline angle is measured between the intake and exhaust lobes. It’s important because it affects when the valves open and closes in relation to the piston’s position.

Conclusion

The best cam for 5.3 Vortec engines is the COMP Cams 17001 Xtreme Energy Camshaft. This cam has been designed specifically for use with 5.3 Vortec engines and will provide an increase in both power and performance.
