Performance snapshot by engine
4.3L V6
Power and torque were roughly around 165 horsepower and about 260 lb-ft of torque. Transmission options typically included a 4-speed automatic or, less commonly, a manual transmission in certain cab/drive configurations.
5.0L V8
The 5.0-liter V8 offered more than the V6, with power generally in the upper hundreds of horsepower range for the era and torque in the mid-range as well. Expect roughly 180–190 horsepower and around 260–300 lb-ft of torque, paired with GM’s 4-speed automatic or, in rare cases, a manual option.
5.7L V8
The 5.7-liter V8 was the most common upgrade for those seeking stronger pulling power, especially in 4x4 models. Typical figures hovered in the area of about 210–230 horsepower and roughly 320–350 lb-ft of torque, with the 4L60/4L60E automatic transmission commonly backing it up.
Diesel option in the 1992 K1500
Diesel power was not a standard or widely available option on most 1992 K1500 half-ton pickups. GM did offer diesel engines on some heavy-duty C/K trucks, but the 1500 line was predominantly gasoline-powered in that year. If a 1992 K1500 did have a diesel, it would be a rare, uncommon configuration and not representative of the typical K1500 lineup.
How to identify the engine in a specific 1992 K1500
To confirm the exact engine in a given vehicle, use these steps. Before you begin, note that the engine under the hood can vary even within the same model year based on options and production changes.
- Check the RPO (Regular Production Option) sticker in the glovebox for the engine code. It will indicate the engine type and displacement.
- Examine the engine block for displacement markings (for example, 4.3, 5.0, or 5.7) stamped on the valve cover or cylinder head area.
- Decode the VIN: the 8th character on older GM VINs often corresponds to the engine family or displacement; cross-reference your VIN with a GM engine code guide for that year.
- Consult the original window sticker or service manual for an exact factory specification tied to that particular vehicle.
Using the above steps will help you accurately determine which engine your specific 1992 K1500 has, regardless of common configurations discussed above.
Summary
The 1992 K1500 offered several gasoline engines, with the 5.7L V8 being the most common powerplant, complemented by a 4.3L V6 and a 5.0L V8 in other configurations. Diesel was not a typical option on most 1500 models of that year. To verify a specific truck’s engine, check the RPO sticker, engine stamping, and the VIN to confirm the exact displacement and engine family.
