You think this really is brand new??

its a scam if they say its 13 years old i ran the numbers. The engine was built in 2009 and was shipped to the military in 2010.

Its very possible it was unused in the military, but i caution you strongly about buying any engine with military assignment. They are not legally allowed to sell them to the public without being decommissioned as military and defense engines are not emissions compliant. They are higher power and dont have to meet on road emissions - therefore by you buying one you are essentially deleting whatever you put it in. The buying of military surplus unused engines is a very large grey area if they dont have a hole in the block.

most defense spec engines wont function in a road vehicle anyways as many parts are different.
