How Many Camshafts Does A Hemi Have – An Expert Guidelines

How many camshafts does a Hemi have? Generally, according to the difference between SOHC (Single Overhead Camshaft) and DOHC (Dual Overhead Camshaft), a Hemi engine has one or two camshafts. It also can vary in terms of different aspects.

The camshaft is responsible for opening and closing the cylinders’ valves, allowing the engine to breathe. Today, we’ll disclose the exact number of camshafts used in the Hemi engine.

How Many Camshafts Does A Hemi Have?

In this section, we’ll discuss in detail to answer the question. Additionally, we’ll answer the question and provide proper guidelines on how many camshafts in a V8 and the numbers of camshafts in different versions of Hemi engines.

The number of camshafts in a Hemi engine can vary depending on the different types of engine. This article will give you the proper upgrade concept and understand the right camshaft for your engine. You can also know what size of the camshaft is right for your vehicle.

Let’s get started –

So far, there are three different types of Hemi engines built. Thus, they can be classified into 3 generations: 1st generation 1951 – 1958, 2nd generation 1964 – 1971, and the 3rd generation started from the beginning in 2003 to the present.

In the third generation, there are typically four types of Hemi engines such as 5.7L, 6.1L, 6.4L, and 7.0L. Each engine has different numbers of camshafts depending on its engine configuration and setup.

Before going into depth, we need to know how many camshafts consist of a four-cylinder. There is only one camshaft in an i4 (four-cylinder) SOHC engine, whereas V8 and V6 engines have two.

On the other hand, a DOHC i4 engine has two camshafts, whereas V8 and V6 have four camshafts. If it is an overhead camshaft (OHC) engine, there might be 3 – 5 valves per cylinder.

Now, before determining how many camshafts in a 5.7 Hemi, we need to know about the SOHC or DOHC of an engine and the engine version.

Let’s look at the number of camshafts used in the 5.7L V8 Hemi. If it has a Dual Overhead Camshaft setup, there will be four camshafts, or if it’s a Single Overhead Camshaft, it will have two camshafts.

Have a look at the table of numbers of the camshaft in Hemi engines depending on the generation and configuration.

How Many Camshafts Does A 6.4 Hemi Have

There are two camshafts in a 6.4 Hemi if the engine is SOHC setup, one for the intake valves and one for the exhaust valves. On the contrary, there will be fo4ur camshafts for the DOHC setup.

How Many Camshafts Sensors Does A 5.7 Hemi Have

Camshaft sensors determine the exact location of the camshaft in your engine. Modern engines typically have one camshaft sensor on each camshaft. Some cars may only have two camshaft sensors.

Conclusion

So far in the discussion, through the article, we have answered the question – how many camshafts does a Hemi have. There are some important things you need to pay attention to when finding out the number of camshafts in the Hemi engine: the type of engine version and the configuration of the engine setup (SOHC and DOHC).

To keep your camshafts in good condition for longevity, you need regularly clean and lubricate the camshaft and its bearings and inspect the camshaft for wear and damage. Additionally, avoid high engine speeds and load levels, and use quality engine oil.
