The 1971 Pontiac Firebird Trans Am 455 and the 440-powered 1971 Dodge Challenger represent two iconic muscle cars from the early 1970s, both known for their powerful engines and aggressive styling. Here's a comparison between the two:
# # # **1971 Pontiac Firebird Trans Am 455**
- **Engine**: The Trans Am 455 was equipped with a 455 cubic inch (7.5-liter) V8 engine, specifically the 455 HO (High Output) version. This engine produced around 335 horsepower and a substantial 480 lb-ft of torque.
- **Performance**: The 455 HO engine gave the Trans Am impressive acceleration and strong mid-range power, making it a formidable contender on the street and track. It was known for its torque-heavy performance, providing great straight-line speed.
- **Design**: The 1971 Trans Am featured the iconic "shaker" hood scoop, a distinctive design element that added to its aggressive look. The body design was sleek and aerodynamic, with a bold front end and a rear spoiler.
- **Handling**: The Firebird Trans Am was praised for its handling, thanks to a well-tuned suspension that provided a good balance between ride comfort and cornering ability. The Trans Am was considered one of the better-handling muscle cars of its time.
# # # **1971 Dodge Challenger 440**
- **Engine**: The 1971 Challenger could be equipped with a 440 cubic inch (7.2-liter) V8 engine, with two main versions available: the 440 Magnum and the 440 Six Pack. The Magnum produced around 370 horsepower, while the Six Pack, with three two-barrel carburetors, pushed that figure closer to 390 horsepower.
- **Performance**: The Challenger 440, particularly the Six Pack version, was known for its raw power and straight-line speed. It delivered a more aggressive powerband, making it a favorite among drag racing enthusiasts. The 440 engine was famous for its high-end power and the distinctive sound of its exhaust note.
- **Design**: The Challenger had a more muscular and aggressive appearance, with wide stance and bold lines. It featured a classic long hood and short deck design, with various options for stripes and decals to enhance its look. The "R/T" (Road/Track) package added to its performance-oriented design.
- **Handling**: The Challenger was more of a straight-line performer, with handling that was adequate but not as refined as that of the Trans Am. It was heavier and larger, which made it less nimble in corners but incredibly stable at high speeds.

# # # **Conclusion**
Choosing between the 1971 Pontiac Firebird Trans Am 455 and the 440-powered 1971 Dodge Challenger depends on what you're looking for in a muscle car. If you value handling and torque-rich performance, the Trans Am might be the better choice. On the other hand, if raw power and straight-line speed are your priorities, the Challenger, especially with the 440 Six Pack, would be the way to go.
