Sometimes you are forced to buy a new 454 camshaft and other times, you simply want one to increase performance. Whichever boat you find yourself in, you can treat your Chevy right with the best cam for stock 454 engines. We perform a complete review of the 454 camshaft selection available to you so that you can find the ideal replacement.

What is a Camshaft?

The camshaft is located near the top or center of the engine. Itโ€™s part of the valve train, allowing fuel and air into the combustion chamber. It also moves the exhaust gases away after the fuel burns. Modern engines will have up to four camshafts.

When the camshaft rotates, the lobes move up and down. DOHC engines use each rotation to cause the valve to push down, which opens the cylinder. With SOHC or pushrod engines, the cam lobe (or pushrods) pushes the rocker arms to open the valve. When the lobe rotates even further, the valve spring causes the valve to close back up.

The 454 Chevy camshaft operates much the same as the modern models, but it is not considered DOHC or SOHC because it is not overhead. Because of this unique design, the 454 cams are harder to replace them some newer models.

Your vehicleโ€™s camshaft is connected to the crankshaft with the help of a timing belt or chain. Pushrod engines use timing gears. Camshaft gears contain twice as many teeth as crankshaft gears, allowing them to rotate half of the speed.

You will notice that there are four camshaft strokes. These are known as the intake, compression, power and exhaust.

What is the Stock 454 Engine?

The Chevy Big Block engine came in many sizes, with the 454 ranking as one of the best. Considering how many engines Chevy has made, that is saying something. Originally, the 454 engine was available in these vehicles.

  • 1970โ€“1974 Chevrolet Corvette.
  • 1970โ€“1975 Chevrolet Chevelle.

  • 1970โ€“1976 Chevrolet Caprice.
  • 1970โ€“1975 Chevrolet Monte Carlo.
  • 1971โ€“1972 GMC Sprint.

Itโ€™s known for its use in muscle cars of the 1970s, but it also has a solid reputation in the pickup segment. The 454 engines were available in some 1-ton Chevy trucks. Even though these engines are no longer installed from the factory in Chevy vehicles, they are still commonly purchased as a replacement by enthusiasts. You can also find a variety of parts that work with the 454 engine, making it a top choice for anyone looking to increase performance.

Benefits of Replacing the 454 Camshaft

Once youโ€™ve upgraded your exhaust and your cold air intake, itโ€™s time to consider a new 454 cam kit. With this addition, you can increase the timing and duration of the valve opening.

When this occurs, the performance of your motor is heightened. Once the job is complete, you might notice some more horsepower, better acceleration, improved fuel economy and overall increased torque.

Hopefully, you are replacing your 454 camshaft because you want to. However, there are also times when a cam replacement becomes necessary.

Signs of a Failing 454 Big Block Cam (bbc camshaft)

The camshaft is an essential part of your Chevy engine. When the 454 cam starts to go bad, you might notice these symptoms.

  • Backfiring or popping noises.
  • Cylinder misfire occurring at either low or higher RPMs.
  • Tapping noise coming from the valves.

Why do BBC camshafts go bad? Sometimes the cam fails because of bad bearings, worn lifters or worn-out lobes. If the camshaft is broken, it could cause damage to the top of the motor. You donโ€™t want to pay for new connecting rods, pistons, valves or a cylinder block.

As with any major engine issue, if something is wrong, it should be looked at immediately. Allowing any vital component to fail only leads to more extensive and costly engine repairs.

Frequently Asked Questions (FAQs)

Which is better: a 350 or 454 engine?

For most passenger vehicles, the 350 is going to be better. Itโ€™s an efficient yet powerful small block Chevy engine. However, if you have a performance car or truck, you will prefer the additional power provided by a 454 engine.

Is the 454 a good engine?

Enthusiasts continue to prefer the 454 engine because of its power and performance. It is a favorite among restorers because there are so many compatible aftermarket parts to choose from. Plus, itโ€™s available in many muscle cars that have become favorites for collectors.

How can I get more power out of a 454?

Start by upgrading your air intake and fuel system. The more fuel and air that gets into the big block engine, the more power you create. Consider upgrading the stock exhaust with something high-flow instead.
Additionally, you can replace stock timing parts with aftermarket components designed for racing. When all else fails, add a supercharger.

If you do the job yourself, you can save a lot of money because you will only need to buy the parts. The cam typically runs around $500, with lifters adding another $500. Donโ€™t forget that you will also need gaskets, oil, a filter, cleaners, sealer and other miscellaneous items.

Can I drive with a bad camshaft?

A damaged camshaft can lead to serious engine issues. If you want to avoid more costly repairs, itโ€™s best to stop driving immediately and have the cams looked at.

Otherwise, you might need to replace connecting rods, pistons, valves, the cylinder block and head or the crankshaft. Depending on how much your vehicle is worth, it might just be the end of its life.

How much horsepower does a cam add to a 454?

A cam can add about 52 hp to a 454 as it responds quite well to the cam upgrade.

What does an oversized cam do?

You can put more air and fuel into the cylinder with an oversized cam by opening the intake valve wider. Thus, the greater the cam, the more fuel it will allow.
