1972 duster 340 value / worth ?

Here is my warning to you. I did a similar thing you are thinking. Back in November I bought a 1972 Duster that had been 340/727 swapped with 8-3/4 rear as a run and drive. Only caveat was it had had a dash fire. Not a big deal I thought, it runs and drives, that’s half the battle and wiring harness is available. I bought the harness and 80% of the parts back in November and December, and January, etc. Now some of those parts aren’t available. By the way, I had to rebuild rear axle, top of engine, brakes, suspension, and still have whole interior to replace. I’m already in this for more than a legit done car would have cost and I am still working on putting it together.
