The 1971 Chevrolet Corvette LS5 Coupe represents the last era of high-compression big-block authority before tightening emissions reshaped the segment. This matching-numbers example features a 454 cubic-inch V-8 and benefits from a documented body-off restoration. Finished in 2010 Lexus Matador Red, it combines factory muscle character with carefully integrated mechanical upgrades.
Exterior Design
The C3 silhouette remains defined by its long hood and tapered rear deck. Chrome bumpers frame the nose and tail, reinforcing its early-1970s identity. This example wears Matador Red paint applied by Silver Falls Auto Body, adding depth to the sculpted fenders. Rally wheels and raised-white-letter BFGoodrich Radial T/A tires complete a period-correct stance.
Interior
Inside, the cabin reflects a comprehensive refurbishment with new genuine Tan leather upholstery and trim. A fresh dash pad, console, and door panels restore factory presentation. The tilt and telescopic steering column improves driving position flexibility. Moreover, new wiring, vacuum lines, and power window assemblies modernize functionality without altering the original layout.
Performance
Power comes from a matching-numbers 454/365 HP LS5 V-8 delivering 365 hp/370 PS and 465 lb-ft/630 Nm of torque. Portland Engine Rebuilders handled the engine rebuild, while a Turbo 400 automatic manages output. A Positraction rear axle ensures effective traction under load. Consequently, the LS5 delivers broad torque and relaxed highway manners typical of Chevrolet’s big-block formula.

Upgrades extend beyond the drivetrain. Steeroids rack-and-pinion power steering replaces the original system for improved precision. Four-wheel power disc brakes and renewed suspension components enhance confidence. Additionally, a Dewitts heavy-duty radiator with dual electric fans supports thermal stability, while a Concept 1 serpentine system updates accessory drive efficiency.
Market Context & Rivals
In 1971, Chevrolet positioned the LS5 between the small-block LT1 and the rarer LS6. Its original MSRP hovered around $5,500, competitive with the Ford Mustang Boss 351 and Plymouth Barracuda 440. Unlike those rivals, the Corvette offered independent rear suspension and fiberglass bodywork, reinforcing its sports car identity over pure pony car aggression.
Production for 1971 reached 21,801 Corvettes, with big-block cars representing a smaller share as insurance costs rose. Today, matching-numbers LS5 coupes occupy a stable collector tier. Values typically range from the mid-$40,000s to over $70,000 depending on restoration quality and documentation, placing them below LS6 examples yet above most small-block counterparts.
Ownership & Value Trends
Ownership appeal centers on accessible big-block performance with manageable maintenance complexity. Parts support remains strong through specialist suppliers, and the Turbo 400 is widely regarded for durability. As emissions-era horsepower declined after 1971, early C3 big-block cars gained renewed attention. Well-restored, correctly documented examples continue to show steady long-term appreciation.
Summary
This 1971 Chevrolet Corvette LS5 Coupe blends factory big-block specification with thoughtful mechanical upgrades. Its restoration quality, matching-numbers drivetrain, and period-correct presentation position it as a compelling entry into early-1970s Corvette collecting.
