ok so it was warm today and i went to local pisk and pull to look around.i found a 62 valiant with aluminum / 6 and push button auto .my question is what is it worth,should i buy it and build it for my 69 dart,or put it back for a rainy day.i can get both engine & trans for about 250.00 and no it doesnt run but turns over by hand.what size would it be.
