Holley’s display at SEMA 2025 was massive, but the car that stopped people in their tracks was a 408-mile 1995 Z28. This wasn’t just a parked survivor; it was a controversial statement. Holley took a pristine, showroom-fresh F-body and tore it down to turn it into a rolling showcase of their engineering ecosystem.
Reliving The Glory Days
The choice of this platform wasn’t random. When the fourth-gen Z28 debuted, its LT1 helped reignite the modern horsepower wars, paving the way for the LS era. This build is about capturing that heritage while injecting serious next-gen capability. To do that, the team pulled the original 275-horsepower V8 and T-56 manual. In their place, they dropped in a supercharged LT4 crate engine backed by a 6L80E six-speed automatic transmission.
Complete Control
Swapping from a manual to an auto might seem odd, but it allowed Holley to flex the muscles of their Terminator X Max system. The ECU handles the engine management while seamlessly integrating the 6L80 control, proving that a complex Gen V swap can be made straightforward. The drivetrain is supported by a full suite of Holley upgrades, including a digital dash, accessory drives, and a robust fuel system to feed the supercharger.
Chassis Engineering
The 1995 Z28 now handles and stops like a modern exotic. The front wheel wells are stuffed with BAER 6S brakes and massive rotors, supported by Detroit Speed Engineering (DSE) suspension geometry and QA1 double-adjustable coilovers. Out back, a DSE FN988 center section with a Truetrac differential puts the power down through a Gear Effects 9-inch housing. Rocket Racing 18-inch Flare wheels wrapped in sticky Toyo R888R rubber ensure the car has the grip to match its new power output.
The 1995 Z28 Blueprint
Visually, the car mixes 1990s Trans Am road-racing cues with modern ZL1 aggression, highlighted by a 3D-printed prototype splitter. This build is more than just a showpiece; it is a rolling blueprint for what happens when fourth-gen history meets modern innovation. It’s an ambitious project that is sure to upset the preservationists, but it proves exactly what this platform is capable of.
