First-gen Firebird 400 survivors are getting rarer and the market has finally stopped pretending barn finds need concours treatment. This 1967 ragtop sits at the inflection point where authenticity commands more money than a nut-and-bolt restoration—and that shift matters.

Colorado custom builder Don Diltz spent years on this restomod—Dynacorn steel body in Dodge Viper Snakeskin Green, Ram Jet 502 with fuel injection, Chris Alston chassis with Mustang II front geometry, and a 6-speed manual. It's the kind of build that respects the '69's lines while ditching the period-correct compromises.
