07 Differences and Similarities Between Silverado v6 Vs v8

Chevy Silverado v6 and v8 engines are some of the most popular and loved engines among automotive users.

They offer some of the best performance for trucks and have developed into a rivalry among truck lovers as to which one is the best for the Silverado truck.

Both of them have some ups and downs.

So, it’s a little bit tough to choose one of them.

In subsequent paragraphs, we shall discuss the differences between the Silverado v6 and v8 engines, highlighting the pros and cons of the engines and answering some important questions you may have about the engines.

What Does ‘V’ Represent in a Silverado V8 and V6 Engine?

You may be wondering what the V in the v8 and v6 or other engine configurations mean.

It is not as complicated as you may think.

The V is simply the internal configuration of the engine.

The V means the way the cylinders are aligned within the engine.

They are aligned in a v- shape around the crankshaft.

There are many variants of the v engine, from the v2 to v12 engines.

A v12 engine will mean an engine with two rows of 6 cylinders each that surround the crankshaft in a v shape.

The rows are usually with an equal number of cylinders.

The equal number of rows on each side helps to improve the balance of mass in the engine for better performance.

07 Differences and Similarities Between Silverado v6 Vs v8

The v engines, as earlier established, are engines with an equal cylinder row surrounding the crankshaft.

It means that on a v6 Silverado engine, you will have two rows with three cylinders around the crankshaft, while the v8 will have two sets of rows with four cylinders surrounding the shaft.

You may be wondering if the numbers of cylinders are the only differences between the v6 and v8 engines.

Both engines are similar, in that they work the same way, relying on internal combustion, gasoline ignition, and so on.

In subsequent sub-paragraphs, we shall list and examine the differences to consider when considering the purchase of a v6 or v8 engine.

01. Specification

There are differences in the designs of the Silverado v6 and v8 engines.

The Silverado v6 engines are built with 6-cylinder chambers surrounding the crankshaft.

They produce an output power of 285 hp, and a torque of 305 lb-ft

It will usually have an engine speed of 5800 rpm max.

On the contrary, the v8 engines are built with eight-cylinder chambers around the crankshaft.

This means that they can produce more horsepower than the v6 engines.

The v8 engines have an output power of 355 hp and a torque of 383 lb-ft.

These are the obvious differences in the design of the V6 and v8 Silverado engine.

02. Towing Capacity

The Silverado v8 has a better towing capacity than the v6.

Two factors that affect towing capacity are the output power and torque.

The higher the horsepower and torque, the higher the towing capacity.

The 6.2L EcoTec3 V8 has an output power of 420 hp and a torque of 460lb-ft.

They have a towing capacity of 13,300 lbs.

In addition, the 5.3L EcoTec3 V8 has an output power of 355hp, a torque of 383lb, and a towing capacity of 11,200 lbs.

In contrast, the v6 engine cannot rival the v8 in raw power and will have a lower towering capacity.

The 4.3L ECOTEC3, V6 with an output power of 285hp and 205lb-ft torque will have a high capacity of about 7,900 lb.

03. Fuel Economy

If you are getting your Silverado for fuel economy, then we recommend the Silverado v6.

The Silverado v6 has been long recognized as one of the best fuel economy trucks available.

Regardless of the model, brands or other factors, the V6 is built to be more fuel-efficient than the v8.

Fuel economy will mean using a small amount of gasoline to produce horsepower and torque.

Larger engines will require more cylinder chambers and, therefore, more gas consumption to produce power and torque.

Whether the Silverado truck is driven on the highway or city, the v6 engine will have a gas mileage of 18mpg to 30mpg.

While the Silverado v8 has a gas mileage of around 16mpg and 22mpg on highway or city roads.

04. Handling

The Silverado v6 has better handling and is more stable, especially when driving through corners.

Their two lesser cylinders mean they are smaller, more stable, and easy to drive.

A v6 will usually weigh around 6900lbs  which is light compared to the v8.

On the other hand, the Silverado v8 weighs more, and its two extra cylinder means they are bigger and will add more mass to your Silverado truck.

The Silverado v8 engine weighs around 7100lbs, an extra 200lbs more than the v6.

The Silverado V8 will find itself drifting during a ta sharp turn, unlike the Silverado v6 truck.

05. Sound

You can expect the Silverado v8 to be noisier than the v6 engines.

If you enjoy a noisy car, you should get the Silverado v8.

The growing noise results from the different timing it takes to fire each cylinder of the v8.

Its connecting rods are designed to be 90 degrees apart.

The v6s are quiet in comparison with the v8s.

06. Cylinder Bank Angles

The cylinder bank angles are the angles between the cylinder.

The Silverado v6 engines have a bank angle of 60 and 90 degrees.

Some v6 may also come with 120 degrees.

Regarding engine balance, 60 degrees are the optimal angle for the v6 engine.

The Silverado v8 has a cylinder bank engine of just 90 degrees, which is not that balance and leads to uneven balancing and misfiring.

This is also responsible for the growling noise you hear from the Silverado v8.

07. Maintenance Cost

The v6 engines are easier to maintain than the v8.

They are built with fewer parts and are more affordable to replace or repair.

Its bigger counterpart, the v8, is a bigger engine with more spare parts.

This means more issues to deal with when repairing or replacing.

Although, the maintenance cost factor should not be a singular reason to buy any, as both well-managed engines have a long life span.

It is something to consider in the longer run.

You must consider the advantages and disadvantages of each and match them with your conditions and needs.

The automotive market seems to be shifting towards the v6, but the power of the v8 has made it unrivaled and relevant in today’s market.


Are v6 more reliable than v8?

This depends on many factors, and why you are choosing the engines.

It is generally believed that the v8, especially the 5.3-liter engines and 5.7-liter engines, have more mechanical power than v6 engines like the 3.8l and require little thrashing making the v8 more reliable in acceleration and overtaking.

If you are looking at fuel economy, then the v6 is more reliable.

Does V6 last longer than V8?

If you use your truck for heavy-duty activities like towing and so on, we recommend you get a v8 engine.

They are built roe activities like this and will have a better life span doing so.

Using a v6 engine for such activities will drastically affect stress on the engine.

Using a v6 for conservative tasks gives you longevity and better mileage.

Does a v8 consume more Gas than a v6 Engine?

The v8 engines are much larger, with an eight-cylinder chamber than the v6 engines.

They require much more exhaust gas than the v6 engines to function properly.

This means you are more likely to get good gas mileage on your v6 than on the v8 engine.

The reason is that few activities require the exhaust gas in the v6 or fewer mechanical movements.

Why do V8 engines sound different?

You are likely to hear growling sounds from your Silverado v8 engines.

This is a normal sound in the engine.

They are caused by the cross-plane crankshaft that is adopted in v8.

These crankshafts are designed with connecting rods 90 degrees apart, causing the engine to fire its cylinder at different intervals.

Therefore you hear the growling sound.

Is the v8 engine going away?

The answer to this question is subjective.

However, we can expect more technological improvements as the world moves to an energy-efficient power source.

Many countries are looking into new ways to do so, with many projecting to achieve this by 2035 onward.

Although, we are unsure when they are likely to achieve this.

Why are v8 engines loud?

The movement of the piston in the engine cylinder creates pulses of air pressure that are exited through the gas exhaust.

Every pulse produces its tone, but because each cylinder in the v8 firs at a different time, they produce much louder sounds.


When considering purchasing either a Silverado v6 or v8 engine, we recommend that the buyer consider the pros and cons of the engines.

The points listed above should not be considered in isolation but collectively.

Also, we recommend that they consider the use and conditions of the road before purchase.

Where the buyer is more interested in power, torque and related factors, the Silverado v8 is the best.

However, where the buyer is interested in fuel economy, handling and so on, we recommend the v6 engines.
