You'll need to find the engine's RPO code (a three- or four-letter code found on a sticker in the engine bay or on the vehicle's specifications) to determine the exact horsepower and torque ratings. Once you have that code, you can consult a Chevrolet parts catalog or online resources specializing in classic Chevy vehicle information to find the specific specs.
Without the RPO code, providing precise horsepower and torque figures is impossible. However, expect the horsepower to generally range from roughly 230 to 275 hp, and torque to be in the 385-400 lb-ft range. This is just a broad estimate; the actual values could be higher or lower depending on the specific engine's configuration.
