Its messed up to be honest. I've got the 5.3 liter setup from the accessories perspective. What's really messed up about the setup? It uses the old 1993 TBI 5.7liter A/C compressor vs the LS1 5.7liter mini compressor......

Its currently got the 6.0 liter truck intake

hmm....waterpump.....waterpump.....never thought about that....ugghh....will take a look tomorrow morning
