Default Lsx 5.3l

I'm trying to get the lingo down, I'm straight on most of the LS1, 2, 3, 6, 7, 9 engines. Where does the 5.3L iron or AL fall in? The motors that are fairly cheap from trucks, are they LS4? I tried looking and I couldn't get a name i can easliy search for to find more information on it.

The 5.3 iron block in my Z-71 is a LM7. Not sure about the aluminum 5.3 though.

Wikipedia for the win. Explains it all. For the most part nobody uses the 6.0 or 5.3 codes since there are a few with no real differences, just say 5.3, 6.0, etc....
