* - For the 4.5 versions indicated, later engines had decreased compression of 8.0:1.

Note: While some of the HP figures don't seem to make sense, this was the best information I could find. Most notably is the 6.3's rated horsepower, as well as values for the 3.5 and 4.5. 3.5 and 4.5 engines are rated for the same horsepower by most sources, with the 4.5 engine producing ~20% more torque.
