Those letter don't really stand for anything, they are simply trim lines which have more or less equipment, for example the LS might be a base trim line without power features where as the LTZ might be fully loaded and might even have the biggest more powerful engine includedAs for finding out which one you have, try calling or driving over to your local Chevy dealerthey might help you bestHope i helped.
