To me, the big block a bodies should be much more valuable. My theory, FWIW is that when the folks from classic industries, year one and the like started to produce the parts, they fully understood the limited production and something of a niche market going in and expected less sales. In order to recoup production costs of with less sales projected, prices have to be raised. Any extra sales due to people wanting to make clones is just extra $$$. Personally, I know a B body appeals to me now because there is more of it can get to to work on easier, even with headers, and I don't have nearly the room I used to have in a '71 Duster with my newfound girth. Is american diet and obesity the reason all the vehicles (especially trucks) get larger every year and what is driving up the B body demand? One has to wonder, but probably not. If that where the case, we would be witnessing a stupidly priced C-body market and demand. I also know more people that had a bodies than b bodies when they where new, even one guy locally that still owns his first new car, a '70 340 Duster in need of restoration. I think most of it is driven equally by the remnants of the overpriced Barrett Jackson craze and a lot of the build up of the legend from the mid eighties on through various media.
