Unless you follow some one else's EXACT swap and can do the EXACT labor and get the EXACT deals, there is no EXACT price.

Unless you are a decent fabricator and a great electronics guy, the parts and labor is the bare buy-in price. All 3rd gen hemis are OBDII. Stock harness requires other parts from the vehicle to communicate, like the cluster. Aftermarket harness and computer is not a plug and play. The harness must be tested and installed properly, and the base software is only a rough starting point. Do you have a laptop or scan tool that talks to the computer? Extra money. Do you have the knowledge to set up and modify timing and fuel maps? When you call the tech line, can you speak and understand the information required to diagnose and fix computer issues? Do you know why a circuit voltage drop test is better than an ohms test?

This may sound harsh, but even if you came on here and asked for the cost of a big block swap into a small block 1973 Duster, there would still be a big range of cost. This is with a swap that has been done a lot and the parts and labor are pretty well established. Even then, there will be unknown things that need to be addressed during the swap. The hemi adds at least a couple layers of complexity to it. There is no bolt-in gas tank with pump and sender, there is no bolt-in exhaust, there is the whole computerized fuel and ignition. The answer would probably scare you!
