* 4.3L V6: Around 160-170 hp (depending on the exact configuration)
* 5.0L V8: Around 170-180 hp (again, depending on configuration)
* 5.7L V8: Around 230 hp (likely the highest output for that year)
* 6.5L Diesel: Around 190 hp (though torque was its stronger suit)
You'll need to check the vehicle's documentation (owner's manual, vehicle identification number (VIN) decoder, or the engine bay itself) to determine the specific engine and then look up its horsepower rating.
