Others are remembered because they were built without compromise. The 1971 Ford Boss 351 belongs firmly in the second category. Produced for just one model year, the Boss 351 represented the pinnacle of Ford\u2019s naturally aspirated small-block performance during the golden era of American muscle. Finished in striking Bright Blue Metallic over a black interior, this R-Code example has been lovingly cared for throughout its life, spending 47 years with its previous owner before joining its current caretaker three years ago.<\/p>\n<p>With only 1,806 Boss 351s produced for 1971, finding a matching-numbers example that remains rust-free while including its original take-off components is becoming increasingly uncommon.<\/p>\n<p>Showing just 51,526 miles, this rust-free Boss has received a carefully planned performance refresh approximately 600 miles ago while preserving the character that made these cars legendary. Even better, the original components removed during the upgrade\u2014including the intake manifold, Autolite carburetor, exhaust manifolds, distributor, and factory radio\u2014are included with the sale, giving the next owner the flexibility to maintain the car as enjoyed today or return it closer to factory specifications. From its unmistakable Ram Air hood to its aggressive stance and unmistakable Boss styling, this is a Mustang that commands attention wherever it goes.<\/p>\n<p><strong>Why This Boss 351 Matters<\/strong><\/p>\n<ul>\n<li>One-year-only Boss 351 production (1971)<\/li>\n<li>Believed Matching-numbers R-Code 351 Cleveland V8<\/li>\n<li>Factory 4-speed manual transmission<\/li>\n<li>Rust-free example<\/li>\n<li>Long-term ownership history (47 years with the previous owner) l<\/li>\n<li>Performance upgrades completed just 600 miles ago<\/li>\n<li>Original take-off parts included with the sale<\/li>\n<li>Five-volume factory service manual set included<\/li>\n<\/ul>\n<p><strong> Engine &amp; Performance<\/strong><\/p>\n<ul>\n<li>Believed Matching-numbers 351 Cleveland R-Code V8<\/li>\n<li>Four-speed manual transmission f ff<\/li>\n<li>Approximately 600 miles since performance rebuild<\/li>\n<li>Engine bored .030 over<\/li>\n<li>Performance Bullet camshaft closely matching factory specifications l<\/li>\n<li>Holley aluminum intake manifold<\/li>\n<li>Holley carburetor<\/li>\n<li>MSD electronic ignition<\/li>\n<li>Headers<\/li>\n<li>Complete new exhaust system from headers to exhaust tips<\/li>\n<li>Runs and drives exceptionally well<\/li>\n<\/ul>\n<p><strong>Exterior<\/strong><\/p>\n<ul>\n<li>Bright Blue Metallic exterior<\/li>\n<li>Correct Boss 351 graphics and striping<\/li>\n<li>Functional Ram Air hood<\/li>\n<li>Rear deck spoiler<\/li>\n<li>Rust-free body<\/li>\n<li>Chrome and exterior trim present well<\/li>\n<li>Factory Boss styling throughout<\/li>\n<\/ul>\n<p><strong>Interior<\/strong><\/p>\n<ul>\n<li>Black bucket seat interior<\/li>\n<li>Factory center console<\/li>\n<li>Factory three-spoke steering wheel<\/li>\n<li>Manual windows<\/li>\n<li>Non-tilt steering column<\/li>\n<li>New shoulder harnesses professionally restored by Snake Oyl Products<\/li>\n<li>Two new replacement interior door panels included (without upper moldings)<\/li>\n<\/ul>\n<p><strong>Chassis &amp; Wheels<\/strong><\/p>\n<ul>\n<li>Factory manual steering<\/li>\n<li>Front disc brakes<\/li>\n<li>BFGoodrich Radial T\/A raised white letter tires<\/li>\n<li>Additional set of four Goodyear Polyglas tires included<\/li>\n<\/ul>\n<p><strong>Additional Information<\/strong><\/p>\n<ul>\n<li>Believed Matching-numbers Boss 351 R-Code<\/li>\n<li>Original owner retained the vehicle for approximately 47 years<\/li>\n<li>Current owner has enjoyed the car for the past three years<\/li>\n<li>Shows 51,526 miles<\/li>\n<li>Original intake manifold included<\/li>\n<li>Original Autolite carburetor included<\/li>\n<li>Original exhaust manifolds included<\/li>\n<li>Original distributor included<\/li>\n<li>Original factory radio included (currently inoperative)<\/li>\n<li>Five-volume factory service manual set included<\/li>\n<li>Clean Tennessee title<\/li>\n<\/ul>\n<p><strong>Known Imperfections<\/strong><\/p>\n<ul>\n<li>Factory tachometer is currently inoperative, reportedly due to the MSD ignition conversion.<\/li>\n<li>Original factory radio is included but will require repair if the next owner wishes to reinstall it.<\/li>\n<\/ul>\n<p>&#8211;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>1971 Ford Mustang Boss 351 Believed to be Matching Numbers R-Code \u2022 4-Speed Manual \u2022 Bright Blue Metallic \u2022 Original Take-Off Parts Included Some muscle cars are remembered because they were popular.
