1973 Dodge Challenger – 440 Big Block, FiTech Fuel Injection, & Modern Muscle Flair

Turn back the clock and feel the raw pulse of American muscle with this 1973 Dodge Challenger, a bold street machine that blends old-school attitude with modern upgrades. Beneath the aggressive T/A fiberglass hood beats the heart of a 440 Big Block V8—delivering unmistakable performance with every press of the throttle. Paired to an automatic overdrive transmission, this classic muscle car gives you the best of both worlds: blistering acceleration and highway-friendly cruising.

Engine and Performance

The powertrain on this Challenger is a showcase of performance engineering. The 440 Big Block V8 benefits from FiTech fuel injection and a FiTech fuel command center, delivering smooth and responsive throttle with modern reliability. A set of long tube headers feeds a dual exhaust system with electronic cutouts, letting you control the soundtrack of your drive—from a civilized tone to full-throttle fury. An aluminum intake, aluminum radiator with an electric fan, and subframe connectors further enhance both power delivery and cooling, ensuring the big block runs strong even on demanding drives.

Cab and Comfort

Inside, the Challenger is as aggressive as it is refined. A blacked-out interior with vinyl bucket seats delivers comfort with a performance-minded edge. Shaved door handles paired with power door poppers add a custom touch while maintaining functionality. The aftermarket radio provides audio entertainment with modern clarity, subtly integrated into the classic dashboard without disturbing its vintage charm. Whether you’re cruising with the windows down or hammering the throttle, the cabin keeps you connected to the car’s muscle car roots with an edge of contemporary convenience.

Features and Attachments

This build isn’t just about speed—it’s about presence. Finished in a striking sunshine-yellow paint scheme with bold black accents, it’s impossible to ignore. The T/A fiberglass hood, hood pins, and front and rear spoilers nod to Mopar’s racing heritage, while chrome Foose wheels give the Challenger an unmistakably modern stance. Underneath, subframe connectors add structural rigidity, enhancing performance handling. With the battery relocated to the trunk and power steering and brakes in place, this Challenger is as functional as it is fierce.

Operational Assessment

This Challenger fires up with ease and settles into a deep, confident rumble. The fuel injection system operates smoothly, providing quick starts and consistent power throughout the rev range. Steering is tight, braking is responsive, and the electronic exhaust cutouts function properly, offering on-demand aggression at the flip of a switch. The automatic overdrive transmission shifts cleanly, and the vehicle holds strong under acceleration. Lighting, turn signals, wipers, and gauges are in working order, making this a road-ready performer with show car looks. The power poppers work seamlessly, and the audio system delivers clear sound without distracting from the car’s muscle car identity.
