Best Cam for 5.3 With 862 Heads

If you’re looking for the best cam for 5.3 with 862 heads, you’ve come to the right place. In this blog post, we’ll discuss the specs of this combination and what it can do for your engine. We’ll also provide some recommendations on which cam to choose based on your desired performance levels.

The 862 heads are a great option for those who want increased airflow and performance from their 5.3 engine. These heads feature larger intake and exhaust ports than stock, as well as minor porting and polishing to further improve airflow. They also have a higher compression ratio (11:1) than stock 5.3 engines, which means they can extract more power from each combustion cycle.

Paired with the right camshaft, the 862 heads can really open up the potential of your 5.3 engine. A good rule of thumb is to choose a cam that has at least 0.050″ more lift on both the intake and exhaust sides than what came stock in your engine. This will ensure that you’re getting adequate airflow through the heads while still maintaining good low-end torque production.

There are many great aftermarket camshafts available for use with 862 heads, so it’s important to select one that matches your driving style and desired performance levels. If you’re mostly concerned with street manners and low-end grunt, a milder cam like Comp Cams’ XE262AH would be a good choice. For those who want more top-end power without sacrificing too much bottom-end torque, something like Comp Cams’ XR282HR would be worth considering.

And if all-out race performance is what you’re after, then something like Comp Cams’ XR288AR would be an ideal choice (just be prepared for some serious valvetrain noise!).
