Need someone to educate me on 5.7's

That looks like a early car motor. 03-05, same one I have I just upgraded to later valvecovers and coils for looks.

That should help with looking at parts and kits. The early motors were known for valve train issues, so you'd need to beef that stuff up when you build. Also it's pretty likely that your motor has MDS (multiple cylinder displacement) lifters, so you'd want to upgrade to 6.1 lifters and MDS selonoid plugs with some size cam swaps. Usually can makers will tell you if that's the case. Small to med sized cams you can leave them in.

Do you know the history of the motor, or why it was pulled? That may help decide how much "work" you do...
