Dig classic Mustangs? You could buy an old one used, or turn to Classic Recreations. The “continuation” manufacturer has been authorized by Ford (as well as Shelby) to build old pony cars anew, and as promised, it’s just revealed its latest version at the SEMA show.

This time it’s the Boss 429 that’s been revived from 1969, and like the original, it packs quite a punch.

Rather than build it from scratch, Classic Recreations started with an original, restored it to factory condition, and fitted it with an upgraded engine: a massive 546-cubic-inch (9.0-liter) V8 kicking out an even more massive 815 horsepower (608 kW), with Kaase Boss 9 cylinder heads, a MagnaFlow stainless steel exhaust, Worx long-tube headers, and mated to a Tremec manual transmission.

The whole thing’s painted in Vengeance Black and rides on a set of 18-inch American Racing VJ529 modular alloys wearing Michelin Pilot Sport rubber with steam-roller 315 cross sections at the back (225 at the front). Slotted, cross-drilled, zinc-washed rotors with Wilwood six-piston front and four-piston rear brakes to keep it all under control. And the interior features TMI seats, a Lecerra aluminum steering wheel, a completely custom center console, Old Air a/c, and a Kicker Audio system.

If you like what you see, Classic Recreations can build one for you, too – alongside its other offerings that include the Boss 302, Mach 1, and an array of Shelby GT350 and GT500 variants – as well as a solitary CR-1 Camaro. Just don’t expect this kind of muscle and authenticity to come cheap. The company’s continuation Mustangs typically sell for a good $150-250k, and we doubt the new Boss 429 would land towards the lower end of that spectrum.
