Is it a good deal or not

So I currently live in a Alaska and I drive a 2006 BMW x3 and have been looking into getting a truck and I found one and it is a 2014 Ram 1500 Crew Cab · Sport Pickup 4D 5 1/2 ft and has 168,00 miles but has a built motor 8 speed transmission 392 gears runs . And this below is all he has put into it. Comp Cam thumper, hellcat lifters, push rods and springs, phaser limiter, ATI super dampener, clutch fan delete, V6 e fan installed, 6.4l injectors, 6.4l manifold, melling high performance oil pump, All American racing long tube headers 1 and 7/8 , and then the custom tune,95mm throttle body. And all that is around 14k in new parts and was put on 15k miles ago And have been on the fence if I buy or should I keep looking. Is selling for 14k.
