Check craiglist and newspapers in the desert southwest and you will find a second gen Chevelle. I'd do it up like the heavy Chevy with an LS engine, 6 speed manual trans, 12 bolt posi. Oh and that has already been done by one of the big builders and they called it their environmentally friendly 'green' chevelle.
