Mark Worman’s 707 HP Hellcrate Supercharged 1970 Plymouth Superbird Tribute at the SEMA Reveal.

Mark Worman built his reputation on TV catching other people’s Mopar misrepresentations — so when he revealed his own 1970 Superbird tribute, built around a 707-horsepower supercharged Hellcrate engine, at SEMA, the scrutiny was immediate. The Graveyard Carz star knows the line between tribute and restoration better than almost anyone in the hobby. Watch the full reveal and see how the Mopar crowd reacted.

Mark Worman has spent years on television telling other people’s Mopars apart from fakes — as the star of Graveyard Carz, his entire reputation rests on knowing exactly what makes a real Superbird real and what does not hold up, down to the smallest stamped part number. So when he stood up at SEMA to reveal his own 1970 Superbird tribute, built around a 707-horsepower supercharged Hellcrate engine that Plymouth never offered in period, he was walking directly into the kind of scrutiny only an expert like him could survive intact. The reaction from the Mopar crowd watching that reveal tells you almost everything about where this hobby draws its lines between homage and heresy.

Why a Graveyard Carz Build Gets Extra Scrutiny

Graveyard Carz built its entire premise around authenticity — Mark Worman and his team have spent seasons explaining, on camera, exactly why a “numbers-matching” claim does or doesn’t hold up under close inspection. That reputation makes any build he personally reveals a different kind of event than a typical shop project, because the same audience that trusts his judgment on other people’s cars is now watching closely to see how he handles the line between tribute and misrepresentation on his own build.

What the Hellcrate Actually Is

Mopar’s Hellcrate is a crate engine package built around the 6.2-liter supercharged HEMI that powers modern Hellcat and Demon models, packaged with the wiring, computer, and accessories needed to drop it into a classic chassis as a genuine bolt-in unit. Rated at 707 horsepower, it delivers roughly double what a factory 426 Hemi made in period, using forced induction technology that did not exist in any form Plymouth could have offered buyers back in 1970, let alone warrantied for daily use.

Tribute vs. Restoration: A Line Mark Worman Knows Better Than Most

Calling a car a “tribute” rather than a restoration is a distinction the Mopar community takes seriously, and Worman — of all builders — understands exactly why that label matters so much. A tribute openly acknowledges the car isn’t a factory-original Superbird, sidestepping the authenticity disputes that plague cars quietly passed off as something they’re not to unsuspecting buyers. Coming from someone whose show exists to catch exactly that kind of misrepresentation, the label carries extra credibility with the community, in a way it simply would not from a builder without his track record of calling out fakes.

SEMA as the Stage for Builds Like This

SEMA has become the venue where builders unveil exactly this kind of modern-meets-classic project, aimed at an audience that already understands the difference between a period-correct restoration and a resto-mod built to showcase what current technology can do to a vintage body. A Superbird tribute with a supercharged Hellcrate engine is built specifically for that stage — a car designed to draw a crowd and start conversations about where the hobby is headed next, not to pass a numbers-matching inspection.

What 707 Horsepower Does to a Winged Car’s Reputation

The Superbird’s aerodynamic wing and nose cone were designed for NASCAR superspeedways, chasing top speed rather than raw horsepower, so pairing that body with 707 modern horsepower creates a genuinely different kind of car than anything Plymouth built back in 1970. For a car whose entire original mission was going fast in a straight line, giving it nearly double the output it launched with reframes the whole point of the winged design — and reactions to that reveal split sharply along exactly those lines among longtime fans, some calling it brilliant and others calling it sacrilege.
