1973 Pontiac Firebird – LS2 Powered Pro-Touring with Modern Tech and Classic Muscle Attitude

Dive into the perfect union of timeless muscle car design and 21st-century performance with this jaw-dropping 1973 Pontiac Firebird. At its heart lies a 6.0L LS2 V8 engine, mated to a 4L80 automatic overdrive transmission, delivering instant power with modern efficiency. Whether you’re carving through curves or cruising down the highway, this Firebird blends thrilling acceleration with smooth, composed drivability.

Engine and Performance

This Firebird doesn’t just look fast—it delivers in every sense. The 6.0L LS2 V8 is managed by a Holley Terminator X EFI system for optimized fuel delivery and throttle response. Ceramic-coated mid-length headers feed into a full 3-inch mandrel-bent dual exhaust system, producing an aggressive rumble that backs up the car’s menacing stance. The aluminum radiator with dual electric fans keeps temperatures in check, ensuring performance remains consistent, even during spirited driving. Subframe connectors and Hotchkis front and rear sway bars provide a solid foundation, enhancing the chassis for both cornering confidence and overall road feel.

Cab and Comfort

Inside the cabin, modern comfort meets muscle car heritage. GTO bucket seats offer support and style, flanked by custom door panels and a custom center console that elevates the overall look and feel. The B&M Pro-Stick shifter emphasizes the performance DNA, while Classic Instruments gauges keep vital information front and center. Stay comfortable in any climate with Vintage Air heat and A/C, and enjoy your favorite tunes through the Pioneer double din radio, enhanced by an aftermarket sound system complete with subwoofer. Even more convenience is found in the backup camera, seamlessly integrated for added safety.

Features and Attachments

Aesthetically, this Firebird is a showstopper. Finished in a bold blue hue and equipped with front and rear spoilers and a Trans Am hood, it strikes a balance between classic aggression and custom flair. Rolling on 18-inch Forgeline Snowflake wheels—a modern interpretation of a Pontiac icon—it offers a stunning stance paired with performance rubber. Power steering and power brakes, along with Wilwood 6-piston 4-wheel disc brakes, provide exceptional control, while custom core support braces improve structural integrity. Every detail of this build has been carefully curated to deliver both form and function.

Operational Assessment
