Holley’s 408-Mile 1995 Z28 Build Debuts At SEMA 2025

This 408-mile 1995 Camaro served as the centerpiece of Holley’s massive display at SEMA 2025. A remarkably preserved F-body survivor, the car received much more than just a simple refresh. The plan was to transform what is essentially a time-capsule Chevy into a fully modernized showcase of Holley engineering.

The choice of platform is no accident. When the Z28 hit the streets in 1993 with its 275-horsepower LT1, it didn’t just beat the Fox-body Mustang, it helped relaunch the modern muscle-car era. That spark eventually carried through to other models like the SLP SS Camaro, Pontiac Firehawk, WS6 Trans Am, and ultimately paved the way for the LS-powered fifth-gen comeback. Capturing that heritage while injecting next-gen capability was the mission behind this build.

To do that, Holley removed the stock LT1, dropped in a supercharged LT4 crate engine, and paired the new mill with a 6L80E six-speed automatic. While the car left the factory with a T-56 six-speed manual, the transmission swap allowed Holley to demonstrate the capabilities of the Terminator X Max system and its 6L80 control integration. Backed by a Holley accessory drive, digital dash, fuel system upgrades, and custom mounts, the drivetrain is a rolling demonstration of a complete Holley ecosystem.

The project began back in August, and progress has been intentionally methodical since the Camaro is doubling as a development mule for the company’s new fourth-gen components. With the LT4 and 6L80 installed, the team has tackled multiple packaging challenges, including relocating accessories and refining clearance around the shock tower and cowl. A 302-21 road-race oil pan, standard LS/LT mounts, and a custom 4L80-style crossmember complete the drivetrain fitment. Fuel demands are handled by upgrading to a 1999–2002 LS1-style tank and Holley’s dual-pump module, capable of supporting E85 and delivering consistent flow under boost.

On the chassis side, the team has packed the front fenderwells of this 1995 Z28 with BAER 6S brakes and massive two-piece rotors, supported by a mix of QA1 and Detroit Speed Engineering (DSE) suspension components. QA1 double-adjustable coilovers with remote reservoirs tie into DSE’s quick-ratio steering rack, sway bar, and crossmember. Out back, a DSE FN988 center section, cased in a Gear Effects 9-inch housing, uses an 8.8-inch Ford ring and pinion with a Truetrac differential for strength and reduced gear whine. QA1 coilovers, sway bars, adjustable panhard rods, and a new fourth-gen 9-inch torque arm complete the handling package in the rear. BAER 6P brakes in the rear and Rocket Racing 18-inch Flare wheels wrapped in 315-wide Toyo R888Rs give the car stopping and cornering capability worthy of its LT4 power.

Visually, Holley is channeling 1990s Trans Am road-racing cues blended with modern ZL1 1LE aggression. A 3D-printed prototype front splitter fits the nose perfectly and provides improvements in aero. If reception is positive, it could end up in production. Future updates will highlight additional aero development, LT-swap tips, and new Holley components being test-fit throughout the process.

The goal is for this ’95 Camaro to become more than a SEMA showstopper, but a rolling blueprint for what’s possible when fourth-gen heritage meets next-generation Holley innovation. Stay tuned as this low-mile Z28 evolves into one of the most ambitious LT4-swapped F-bodies ever built, and one to surely upset preservation purists.
