A camshaft is a part of the combustion engine that’s made of metal. Its primary job is to convert rotational energy to reciprocal energy using the pointed cams. Choosing the best cam for stock 454 big block might become frustrating as you’ve to take into account various aspects.
I have reviewed 454 camshaft selection based on rpm range (where the engine performs best and matches the other components of your vehicle)
The 4 Best Cam for Stock 454 Big Block: to increase performance
- COMP Cams CL11-600-4 Thumpr 279TH7 Cam
- Edelbrock 7162 Performer Cam
- COMP Cams K11-242-3 Camshaft Kit
- Lunati Voodoo Cam Lifter Kit
The Benefits of Using a Cam
Enhanced performance: The camshaft is essential in improving the performance of the engine. It operates the intake and exhaust valve and increases horsepower.
High-speed: It increases the operating range of high-speed engines.
Powers Engine: The camshaft lifts the intake valve and exhaust valve to combust air/fuel mixture that powers the engine with ease and efficiency.
Accelerating air/fuel mixture: While rotating, it lets the pistons carry air/fuel intake strokes as the valve lifts. This lift allows the cylinder to combust the mixture and start up the engine.
Opening valves: The overhead camshafts keep the valves lifted for a certain amount of time. The intake and exhaust process is carried out at the exact time without overheating the engine.
The 454 EFI version was rated from 230 hp (172 kW) to 255 hp (190 kW) and from 385 lb⋅ft (522 N⋅m) to 405 lb⋅ft (549 N⋅m) of torque.

Variations of Chevy 454 Big Block
The Chevy 454 engine included three versions. These were LS5, LS6, and LS7. These versions were not publicized, and the LS7 was considered for the Chevelle and the Corvette. These are known as applications with high performance.
Protests indicated that the HP output of LS7 had been underrated in the 1970’s while the muscle cars were in trend.
In order to give you an overall idea of its performance, the early 1970’s were the years of 454 engines. It outnumbered the LS5’s 350 HP and LS6’s 450 HP with success. The increasing emissions caused LS6 to be taken down while in 1973, the LS5’s HP was brought down to 245. 454 was discontinued by Chevrolet from cars and trucks in 1975 and 1996, respectively.

Buying Guide for the Best cams for stock 454 Big Block
The market is full of cams for stock 454. It can be quite tough and hassling to decide the best cam for your car or truck’s 454 engine. In this section, I will discuss the comp cam selection guide to pick the best cam for stock 454.
The camshaft’s duration indicates the amount of power offered to the engine. Therefore, the longer the cam’s duration, the better the engine’s efficiency.
Hydraulic roller-styled steel-made cams are considered the best as they do not wear off soon, ensuring more extended durability with higher HP and less friction.
Higher RPM is what you would want to look for while selecting the cam for your 454. Cams that provide RPM around 5500 are the ones you should go for as they initiate higher HP for the high-speed engine.
Valve Overlap & Lobe Separation
The lobe separation angle is also known as LSA is mainly the angle located in camshaft degrees between the centerlines, or maximum lift points, or of the intake lobes, or the exhaust lobes.
It also affects the amount of valve overlap and therefore they are interconnected with each other in terms of functionality. In the brief period when both the intake valves and exhaust valves are open, then the valve overlap will happen into the lobe separation angle.
The valve lift is the distance between the open position of the valve and the seated position of the valve after it is raised. The height and duration of the valve are connected to the width and shapes of the camshaft lobes.
The valve lift allows more open place in both the intake and exhaust lobes of the cylinder. Later, when the air and fuel will be drawn in, exhaust gases will be pushed out.
It is measured in inches using a dial indicator at the top of the valve. But before doing so, you must have to raise the valve from its seated position.
Cams determine the engine’s performance. Those cams that ensure higher torque and enhanced throttle response are good to go for 454’s.
Select cams that provide better engine sounds and efficiency with durability.

What is a Camshaft?
A camshaft is located on an internal heat combustion engine which is also a device controlling both the expulsion of exhaust fumes and the input of fuel. It has several radical cams and each of them displaces intake or exhaust valves.
There is a difference between the camshaft and the crankshaft. The camshaft is interlinked to the crankshaft through a chain, belt, or gears.
However, the camshaft is one of the oldest parts of the engine and providing service since the invention of the engine. But day by day, it has become a complex system of parts but yet it is a basic component of an engine.

Everyone will welcome this 52 HP addition to their stock 454 engine as it comes with a reasonable jump in peak torque too.
How can I make my stock 454 Big Block faster?
To make your stock 454 faster, you need to ensure more power out of your stock 454 engine and to do so you need to follow these steps as given below:
- Replace the exhaust system of the stock engine with a high flow system.
- Improve or change the air intake and fuel system because more amount of fuel and air will ensure more production of power in your stock 454 engine.

Which is better: a 350 or 454 engine?
If you are having a lightweight or medium-weight car, then a 350 engine can offer you the best experience, especially when you are in for a daily driving role.
