Hi must say this is an awesome site..I have a million well not quite but have questions.. I bought this engine from a friend who bought it from a friend has been a modern art piece in atleast three garages..I know nothing about these engines Im trying to keep it fuel injected and that's where my confusion starts because everybody I have spoken to about these engines are running carbs on them..I have a lot of pictures that maybe you can help me I.D.Engine is a 2007 4.8 out of a truck did not have a starter so some wiring is not there for one..I have a big red wire coming off the alternator does this go to the starter?I also did not get the air duct system so I guess I don't have a maf sensor?Lots of pics lots of questions

casting number off the back of the block 12576178 underneath that it says 4.8 5.3
