2011 iron block truck... Buy it or leave it

[hartleymetalworks]

Wanting to do a lsx swap into my 72 c10. Been looking for a 5.3 for a while. Wanting to install a car intake, and aftermarket pulleys and brackets. Slim oil pan for pb dropmember clearance. Anyways... Found a totaled 2011 chevy truck with lots of front damge.

Knowns:
Most valuable bolted on things are gone (starter, coils, computer, throttle body etc)
Iron block
Front drive brackets busted

Unknowns:
Mileage (carfax says in 10/13 had 21k)
Could any internals be damaged?
Am i overlooking any major valuables that could be missing.
Power steering pump busted
Alternator busted

I can buy motor and tranny (basically going to cut frame in half in front of cab) for 350-400$. Ive read a lil about the newer motors and the few things to overcome vvt and dod. Since im planning on new drives and intake/tb anyways. Should i buy it or leave it???? Help
