Hemi opinions

So ive been reading alot of the hemi swap threads. I have a buddy who owns a towing company. He said i can have my pick of 2 motors for free. One is a 2008 5.7 and the other is a 2014. These are both in the cars still with trans harnesses etc. They both have 60k miles roughly. I just want opinions on which one is the better choice. They are both in chargers btw. Any input is appreciated. Ty. Oh it would be going in a 71 duster
