The 454 engine was available on several Chevrolet platforms, including trucks, SUVs, vans, and other heavy-duty vehicles. It was most often found in the Chevrolet Monte Carlo and Corvette, but it also came on C/K pickups, and coupe-pickup hybrids. But, the 454 is now out of production.
In the first iteration, the 454 was a half-ton engine rated for 240 horsepower and 355 lb-ft of torque. The engine was designed for heavy-duty towing, and it was often found in trucks with rear-wheel-drive. However, most 454s were installed in full-ton trucks. Chevrolet renamed this engine the L19 and kept the same cast iron heads and hydraulic flat tappet lifter cam. The primary update to the Chevy 454 was the use of a throttle-body fuel-injection system. This made the engine more fuel-efficient and boosted its output to 255 hp and 405 lb-ft of torque.
The fourth generation of the 454 is a high-performance version of the C/K series. It borrowed the 454 V8 from the heavy-duty line-up and gave it a much smoother ride than its predecessors. This version was introduced in 1991, and it was built until 1993.
How Much Horsepower Does a 454 SS Truck Have?
The 454 engine was first manufactured in 1970 and produced between 240 and 400 horsepower. It was initially geared for heavy-duty towing, and was most often found in full-ton pickup trucks. In 1987, Chevrolet introduced a fuel-injected version that produced 230 to 255 horsepower and 380 to 405 lb-ft of torque.
During the 1990s, the Chevrolet 454 SS pickup was one of the most popular performance trucks. It borrowed the 454 V8 from GM’s heavy-duty lineup, and featured a quick steering and lowered suspension system. In 1991, the SS engine was upgraded to 255 horsepower, and the truck continued to be produced until 1993. The engine was also paired with a six-speed manual transmission.
In 1991, the 454 SS was equipped with a new 4L80E transmission, which increased horsepower to 255 and torque to 405 lb-ft. The lower gear ratio of 4.10:1 increased acceleration. The 454 SS could run the quarter-mile in 15.6 seconds. That wasn’t too far behind the Camaro IROC-Z, but it was way ahead of the latter.
What Year Did Chevy Put 454 in Trucks?
In 1979, Chevrolet removed the 454 from the half-ton order sheet and made it an exclusive engine for its heavy-duty truck line. In 1987, Chevy added fuel injection (FI) to the 454 to give it a boost. Its name was changed to L19, but the basic design remained the same. It retained a hydraulic flat tappet lifter cam and cast iron heads. The primary update to the 454 was the addition of a throttle-body FI system. As a result, the 454’s output climbed to 255 horsepower and 405 lb-ft of torque.
The 454 engine was produced by Chevrolet for nearly four decades. Its first application was in the 1970 Chevrolet Corvette with 390 horsepower and 500 pound-feet of torque. Later, the 454 engine was fitted with a Holley carburetor, bringing the horsepower and torque ratings to 450. Then, in 1987, Chevrolet introduced a fuel-injected version of the 454 engine and used it in the GM C1500. This version was rated at 230 to 255 horsepower and 400 pound-feet of torque, bringing it up to its current output of 450 hp.
The 454 engine was a true workhorse and was used in a wide range of Chevrolet vehicles. Its performance was legendary and it continues to be used in tow trucks and old Corvettes today.
