How Much Horsepower Does A Cam Add To A 454?

The 454 responded very well to the cam upgrade, as the peak numbers jumped from 376 hp and 482 lb-ft with the stock cam to 428 hp and 507 lb-ft of torque. An increase of 52 hp is always welcome, especially when it comes with a sizable jump in peak torque.

Does a cam increase horsepower?

Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly. You’ll idle slightly rougher with a performance cam, but get a throaty rumble that’s desirable for some gearheads, depending on your vehicle.

How much HP does a high lift cam add?

Our high-lift cam produced 20 more hp and 9 more lb-ft of torque than our identical low-lift version of the same camshaft. Comparing the data, we noticed that the camshafts are almost identical in horsepower and torque until right around 4,200 rpm, where we start to see the lines separate.

What year 454 had the most HP?

1970
The 1970 versions of the Chevrolet 454 were the most powerful, with the LS5 putting out around 360 horsepower and the LS6 delivering about 450 horses.

How much horsepower is a 454 capable of?

It’s the same cast iron block and same bore x stroke. The crate motor features a fairly low (by modern standards) 8.75:1 compression ratio. All rotating assembly is forged. 454 HO crate engines offer 438 horsepower and 500 lb-ft.

What does a Stage 3 Cam do?

Product Description. The LS1 Stage 3 camshaft was designed for enthusiast who want to increase power while maintaining excellent drivability and manners. This cams can be used with stock torque converters, stock rear gears, stock intake manifold, stock exhaust manifolds etc.

Is upgrading camshaft worth it?

Yes. Adjusting the camshafts so the cams are slightly ahead or behind will alter the engine’s performance. Advancing the timing will cause the fuel intakes to open and close earlier, which improves low-end torque. Conversely, retarding the cam will improve high-end horsepower at the expense of low-end torque.

What is considered a big lift cam?

When someone refers to a “big cam,” they mean it has longer duration, not higher Lift. Manufacturers often list 2 different duration values: Advertised Duration is the degrees of crankshaft rotation that the lifter is raised more than a predetermined amount. This predetermined amount varies between manufacturers.

How much HP does a Stage 3 cam give you?

It is a lot more aggressive and worth an additional 20 hp on top of the gains from the 8710 grind or 123 hp over a stock LS3 when combined with a stroker kit.

How much can a 454 be bored out?

That’s because the classic, Mark IV big-block is limited to about 0.100-0.125-inch maximum overbores. On a 454ci engine with a stock, 4.00-inch stroke, a 0.100-inch overbore delivers a 476-inch displacement, while a 0.125-inch overbore will give you a 481-inch Rat.

How much can you stroke 454?

Take a 454, add a 4.250-inch stroke crank along with some 6.385-inch rods and your displacement shoots up to 489 cubes.

How fast is a 454?

But as MotorWeek found out, the 454 SS was still pretty quick. Lots of low-end torque helped the truck sprint to 60 mph in 7.7 seconds, while the quarter-mile took 15.9 seconds.

How much HP did 1970 454 have?

The 1970 LS6 454, factory rated at 450 hp, was exclusive to the Chevelle and the El Camino. It not only gave Chevrolet intermediates more power than the Corvette that year, it was the most powerful engine those cars would ever have.

Which is better a 454 or a 350?

In a light to medium weight car, a 350 will probably offer you the happiest experience, especially in a daily driver role. In a truck, the 454 will probably feel better to your foot. In an all out performance car, the 454 will probably be more likable as long as the car is a straight line car (drag racing etc).

How much horsepower does a supercharged 454 have?

SC HELLION 454
This CBM engine is Supercharged, it puts out 900+ hp @ 6800 RPM’s and 875 ft-lbs of torque using 10lbs of boost.

What does a Stage 2 cam do?

Stage 2: this is typically referred to an engine with a performance cam upgrade as well as the other components within a Stage 1 combination. A typical Stage 2 has generally +20-25% more HP than stock. Stage 4: this would be a moderate compression big bore combination. It includes headwork and more cam than a Stage 3.

What is considered a mild cam?

An RV or towing camshaft, which is considered a mild performance or an economy cam, will often have a narrower LSA, between 112 and 114 degrees. Hot street camshafts usually have 110- to 112-degree LSA, while high performance and racing camshafts will often run between 105 and 108 degrees.

What are the 4 types of cam?

Many different areas make up the practice of complementary and alternative medicine (CAM). In addition, many parts of one field may overlap with the parts of another field.
What are the different types of CAM?

• Acupuncture.
• Ayurveda.
• Homeopathy.
• Naturopathy.
• Chinese or Oriental medicine.

What makes a cam high performance?

Performance cams typically have durations ranging from 220 up to 280 degrees or more. The longer the duration, the rougher the idle and the higher the cam’s power range on the rpm scale. A cam with a duration of 240 degrees of higher will typically produce the most power from 3,500 to 7,000 rpm.

Does advancing cam timing make more power?

Higher engine speed causes greater exhaust-gas velocity, which relates to greater momentum of the exiting exhaust gases. This is why a longer-duration camshaft produces power higher in the rpm range.

How much HP gain with cam swap?

The answer hugely depends on the car’s pre-existing engine and drivetrain.

1. You can expect a gain of about 10% from a performance camshaft.
2. As mentioned, changing the camshaft alone will likely provide about a 10% horsepower boost, although it could be more.
