Common engines for a 1989 Chevy 1-ton included:
* Small-block V8s (e.g., 5.7L/350, possibly a TBI version): These typically ranged from around 180-230 horsepower and 280-330 lb-ft of torque, depending on the specific configuration and carburetion/fuel injection system.
* Larger V8s (e.g., 7.4L/454): These were significantly more powerful, often exceeding 230 horsepower and delivering well over 350 lb-ft of torque. The exact figures again depend on the specific configuration.
* Diesel engines (e.g., 6.2L): These produced lower horsepower but considerably higher torque, ideal for towing. Expect around 165-200 horsepower and 300-400 lb-ft of torque (the exact figures depend on the specific diesel configuration).
To find the precise horsepower and torque rating for your specific 1989 Chevy 1-ton truck, you need to:
1. Identify the engine: Look for an engine code on the engine block itself or in your owner's manual. This code will help you determine the exact engine type and displacement.
2. Consult a resource: Once you know the engine code, you can search online for specifications (like on websites dedicated to classic Chevy trucks) or consult a repair manual for that specific year and model.
Without knowing the specific engine, I cannot provide a definitive answer.
