To find the exact specifications for *your* 5.7L Hemi engine, you need to:
1. Locate your engine's identification number (VIN). This is usually found on a plate on the dashboard or the driver's side doorjamb.
2. Use the VIN to look up your engine's specifications online. Many automotive websites and databases allow you to enter your VIN to retrieve detailed information about your vehicle, including its engine specifications. Chrysler's own website or a reliable parts site would be a good place to start.
3. Consult your vehicle's owner's manual. This document will have the most accurate and relevant information for your specific car or truck.
Without knowing the specific year and model of the vehicle, providing precise specifications is impossible. The above is a generalized representation.
