need knowledge please

Do you know what your 5.7 came out of? Truck? Car? There are a couple of differences between the two. Year model helps too, for example, an '05 truck Hemi does not have MDS whereas, they added it to the '06 trucks (with auto trans). Little things like this (and your intended use of the engine, ie. going in an A body with auto or manual trans?) will help us, help you.
