ID LS1 plz

I am going to buy this motor from a friend. He has had it laying around in his shop for sometime but says he believes it is 03-04 Yukon 5.3 with 4l60e tranny

Can you folks please help me be sure what I am buying? It has 862 heads and says 4.8/5.3 stamped on block.

I would like to know for sure displacement,yr and what you might do to beef up a little ? I plan on putting it in a 1972 Chevy LWB fleetside, Driver with a milage and a little muscle would be great..

Also like to keep it EFI

Thank you
Dan

If there is somewhere I need to look for ID , Plz advise
