The Dynacorn goes for $15,995 fob Oxnard California. (Does "fob" mean that shipping is extra?) That includes the doors and the trunk lid, but no front clip. The Hot Rod story points out that these unibodies are not "ready for paint" from the factory, so in addition to running down all the bits and pieces needed for a full car, you are also looking at a hundred hours of blocking and panel fitment.
Your other option is the typical project car also in need of a complete teardown. Rusted-out '67 fb cores seem to go for $5000 and up. Although the do-it-yourselfer never includes labor in the equation, taking a $5000 core cost and $75 to $100 per hour for a bodyman will buy you 110 to 145 hours of labor to bring that rusty core up to the level of an as-delivered Dynacorn unibody -- i.e., still in need of blocking and panel fitment.
Putting the two options side-by-side, they look pretty even. The tipping point depends on individual tastes.
On the plus side for the gennie, you have a factory-correct foundation underneath all the patch panels, making it more likely that other components will fit without a lot of massaging. You also have a VIN, which is not an insignificant benefit. The advantage of possibly having a reusable set of fenders and hood, vs. all the patch panels and welding that the gennie will need, is probably a push.
On the plus side for the Dynacorn, you have an all-new car when you're done. A plus, to some (i.e., me), is the complete freedom from factory equipment. Painless wiring harnesses, for example, and custom interior. If you're like me and you hate the OE shocktowers, and you want some huge tires, in the 335 mm range, you could go with an Art Morrison Muscle Car full frame chassis. These use fifth gen ("C5") Corvette running gear up front, with rack & pinion, and a coil sprung 9" in the rear (or air springs if you like). According to another story in this same Hot Rod magazine, on an over-the-top '67 Mustang street rod, AME has just prototyped a version of this chassis specifically adapted to the '67 Mustang. Add an aluminum block Cleveland with 428 ci and CHI 3v heads, good for 650-700 hp, and you've got a Ferrari killer for $40,000 - $50,000. That was once the high end of the Classic Stang hobby, but with 351 ci Mach I's going for the mid 50's now -- or 327 Powerglide Crapmaros for that matter -- it no longer is.
