Too nice to use as a parts car? (pic intensive)

Sell the 383, put the 340 in the Demon for now. Look around for the replacement 318 for the Duster and maybe new fenderwells. Just price the inner fender wells, If cheap enough then get them. Put the Duster out there for sale and see what happens?

The 383 is going in my dad's Charger. If I take the 340 out of the Duster, all the suspension, brakes, and K member are going with it.
