Here's why:
* Multiple Engine Options: The 1958 Apache trucks were available with a variety of engine sizes, including the 235 cubic inch six-cylinder, 265 cubic inch V8, and even larger options. Each engine produced different horsepower.
* Transmission & Axle Ratios: The transmission and axle ratio in the truck also affect its performance. A truck with a taller final gear ratio will have a higher top speed but slower acceleration.
* Variations by Model: Even within the Apache line, there were different models (1/2 ton, 3/4 ton, 1 ton, etc.) and each might have had different standard engine options.
To find the specific details you need, you'll have to research based on the following information:
1. Apache Model: Is it a 1/2 ton, 3/4 ton, or 1 ton Apache?
2. Engine: What size engine did it have? (235 cu in, 265 cu in, etc.)
3. Transmission: What type of transmission did it have? (3-speed manual, 4-speed manual, etc.)
4. Axle Ratio: What was the final drive ratio in the rear axle?
Once you know this information, you can search for specific 1958 Chevrolet Apache specifications online (using resources like the Chevrolet website, classic car enthusiast forums, or automotive databases).
