The 1992 Chevrolet 5.7‐liter V8 delivered horsepower that varied by configuration, typically ranging from about 210 hp in the standard engines to roughly 275 hp in the LT1 high‑performance versions. The exact figure depends on the vehicle and engine code.
In 1992 GM offered the 5.7L V8 in multiple formats: a base version with throttle-body injection (common in light-duty trucks and many cars) and a higher‑performance LT1 variant used in Corvette and some sportier Chevrolet models. Here is how the numbers break down.
Variants of the 5.7L V8 in 1992
The horsepower difference hinges on the engine family. The two primary groups were:
Base 5.7L V8 with throttle-body injection (TBI)
Horsepower estimates for this configuration fall in the range commonly seen in everyday use during that era.
- Horsepower: about 210–230 hp
This base variant powered most light‑duty trucks and many passenger cars that year, offering reliable performance for daily driving.
LT1 high‑performance 5.7L V8
The LT1 version was the top‑tier option, used in Corvette and select performance‑oriented Chevrolets, delivering stronger output.
- Horsepower: about 275 hp
This variant helped define GM’s performance image for the era, especially in Corvette and certain sportier models.
Model snapshots (representative examples)
To illustrate practical applications, here are representative figures from key 1992 models that used the 5.7L V8.
- Light‑duty trucks and many passenger cars with the base 5.7L V8 (TBI): around 210 hp
- LT1-equipped performance models (Corvette and select sports Chevrolets): around 275 hp
For exact numbers on a specific VIN or engine code, check the emissions label under the hood or the VIN/engine code sticker on the firewall or intake manifold, since production variants and calibration could affect the precise horsepower rating.
Summary
The 1992 Chevrolet 5.7L V8 covered a horsepower spectrum from roughly 210–230 hp for the standard, throttle-body injected engines to about 275 hp for the LT1 high‑performance version. Always verify the exact engine code (LTI/LT1 vs. base 5.7L) to know the precise figure for a specific vehicle.
