Number matching doesn't me anything with most of these cars. You'd get the same money for your car with the crate engine if not more. I sold my non-matching numbers dart (which originally was a 69 swinger 340, 4 speed, non power with factory air) for 25k. I'm hard pressed that I would have gotten much more, if any, had it been left stock.
I sold my last 340 for 1500 but that was quite a awile ago and it wasn't in the car. If you want top dollar for an engine it has to be in the car and running.
