How much HP does a supercharged 454 Big Block have?
A supercharged 454 cubic inch (7.4 liter) Big Block engine can produce an impressive amount of horsepower (HP). Depending on the specific modifications and tuning, a supercharged 454 Big Block can generate anywhere from 500 to 800 HP or more.
Horsepower Potential of the 454 Big Block
The 454 cubic inch (7.4 liter) Big Block V8 engine is a legendary powerplant known for its massive displacement and torque output. In stock, naturally-aspirated form, a 454 Big Block can produce around 350-400 HP. However, with the addition of a supercharger, the horsepower potential of this engine increases dramatically.
Supercharging the 454 Big Block allows for significantly more air and fuel to be packed into the cylinders, resulting in much higher combustion pressures and temperatures. This, in turn, boosts the engine's power output well beyond its naturally-aspirated capabilities.
Factors Affecting Supercharged 454 Big Block HP
The exact horsepower output of a supercharged 454 Big Block can vary widely depending on several key factors:
- Supercharger size and boost pressure
- Engine modifications (camshaft, heads, intake, etc.)
- Fuel system upgrades (fuel pump, injectors, etc.)
- Engine tuning and calibration
With the right combination of high-performance parts and careful tuning, it's not uncommon for a supercharged 454 Big Block to produce 600-800 HP or more. However, more modest setups in the 500-600 HP range are also very common.p>
Conclusion
In summary, a supercharged 454 cubic inch Big Block V8 engine is capable of generating an impressive amount of horsepower, typically in the range of 500-800 HP or more, depending on the specific modifications and tuning. The massive displacement and forced induction of this legendary engine make it a popular choice for high-performance applications where massive power is required.

How much horsepower can you get out of a 572 big-block Chevy?
The horsepower output of a 572 Big Block crate motor can vary depending on the specific configuration and modifications made to the engine by the manufacturer offering it. However, generally speaking, a 572 Big Block crate engine can produce between 620 to 750 horsepower and 645 to 710 lb-ft of torque.
Does a bigger cam add horsepower?
In most cases, yes, but it depends on the model of the truck and which custom cam you use. With that said, aftermarket cams are designed for high-end performance, so you can typically expect to experience faster speeds after camming a truck. Are Bigger Cams More Powerful? Yes.
What is the most horsepower you can get out of a 454?
The first page of 454 crate motors on Summit Racing ranges from 438 to 720 horsepower, and those are all naturally aspirated. Add forced induction into your build and you could be over 1000 horsepower.
How much HP can a 454 big-block make?
The budget 454 not only managed to exceed 500 hp, but did so in spectacular fashion with peak numbers of 565 hp at 5,900 rpm and 532 lb-ft of torque at 5,400 rpm.

How much HP will a supercharger add?
Keep in mind that a 50-percent power boost is a near-perfect-world scenario, and because superchargers are connected directly to the crankshaft, they do sap some efficiency from the car. On average, adding a supercharger will give you a supercharged horsepower boost of about 46 percent with 31 percent more torque.
How much power do you lose with a supercharger?
However, that boost comes at an upfront cost. Notably, a loss of horsepower of as much as 20%.
What's better, a turbo or a supercharger?
Both turbochargers and superchargers are effective methods to increase the power and performance of an engine. However, turbochargers are preferred over superchargers, as they increase fuel economy, and reduce waste gas emission.
How much HP does a Cammed 454 make?
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.
