I saw a thread before the change that gave the production codes for the "standard" and "h.o." versions of the 5.3 and 6.0. I am interested in the selections offered since '04. What I would like to get is production codes (i.e. L33, LQ9, etc..), V.I.N. identifiers, and the actual differences between the base and h.o. versions of each engine like iron or aluminum heads, iron or aluminum blocks, etc. I tried a search and didn't find much. Thanks.

On edit: Oh yeah, how about stock HP and TQ ratings for each as well. I understand that's alot of info, so a link to the same would work as well. Thanks.
