The 454 TBI was a high-performance engine produced by Chevrolet. In the early 1990s, the company featured the engine in their 454 SS pickup truck. The engine ran on regular octane gasoline. In 1992, the 454 SS pickup had an MSRP of approximately $18,000 to $20,000.
Engine Specifications and Perfomance
The 1992 454 used a V-8, overhead valve engine design. The piston displacement measured 7.4 liters. Maximum power output for the engine was 255 horsepower at 4,000 rpm, and peak torque potential measured 405 foot-pounds at 2,400 rpm. The engine performance was notable, as the 1992 could push a Chevy pickup from zero to 60 mph in 7.1 seconds. In the Chevy pick, the engine could also produce a quarter-mile run in 15.7 seconds, reaching a speed of 87 mph in that time.
The engine featured a TBI, or throttle-body fuel injection design, which was an enhanced, electronic version of a carbureted fuel-injection system. The engine also featured a hydraulic-roller cam. For years, Chevrolet used a flat-tappet cam, but in the early to mid-1990s, the company transitioned to a roller cam, which reduced engine wear and improved engine performance. The overhead valve design used 16 valves, and the drivetrain featured a two-wheel, rear-wheel-drive system.
Dimensions and Weight
Chevrolet paired a 25-gallon fuel tank with the 454 engine. The company also paired the engine with the 1992 Chevrolet 454 SS pickup, which measured 194 inches in length, 76.8 inches in width and 70.4 inches in height. The truck had a 117.5-inch wheelbase, and the rear axle ratio was 3.73 to 1. The truck had a curb weight of 3,839 lbs., and the maximum payload with the 454 engine was 1,023 lbs.
Chevrolet used the 454 in its pickup truck line during the 1990s. From 1990 until 1993, the company produced the Chevrolet 454 SS pickup, which featured the large 454 engine on a short-bed C1500 pickup truck. In the mid-1990s Chevy upgraded the engine, and continued to offer the engine as an option in the Chevrolet Silverado until 2000. In the early 1990s, a four-speed automatic transmission was used with the engine.
