The engine's massive low-end torque made it a natural candidate for racing fuel systems, and when builders started bolting Hilborn mechanical fuel injection onto the Nailhead, the results turned heads at strips across the country. Hilborn injectors — with their individual throttle bodies and open stacks — were the mark of a purpose-built race engine. If your build pays tribute to that era, this badge captures exactly what's under the hood.\u003c\/p\u003e\n\n\u003c!-- PRODUCT INTRO --\u003e\n\u003cp\u003eThis is the Mad4Metal Buick Nailhead Hilborn Injected badge — machined from a solid billet of 6061-T6 aircraft-grade aluminum. The face is CNC cut with the \u003cstrong\u003eNailhead by Buick\u003c\/strong\u003e graphic derived from a period-correct 401\/425 big block photo, capturing the look of a Hilborn-injected Nailhead as it appeared in the mid-to-late 1960s.

Those marks are intentional. They're what separates a real machined billet part from something that was painted, cast in a mold, or made to look like metal. A perfectly mark-free, glassy smooth surface would look like painted plastic. The toolpath lines catch light at different angles depending on where you're standing, and that shifting reflection is the signature of a part that was actually cut on a machine. If you want to bring up the high spots even more, a quick pass with aluminum polish will do it — while keeping the machining character completely intact.\u003c\/p\u003e\n\n\u003c!-- WHERE CAN YOU RUN IT --\u003e\n\u003ch3\u003eWhere Can You Run It?\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eValve covers — passenger or driver side\u003c\/li\u003e\n  \u003cli\u003eEngine fenders \/ inner fender panels\u003c\/li\u003e\n  \u003cli\u003eHood underside\u003c\/li\u003e\n  \u003cli\u003eFirewall\u003c\/li\u003e\n  \u003cli\u003eDashboard or instrument panel\u003c\/li\u003e\n  \u003cli\u003eGlove box door\u003c\/li\u003e\n  \u003cli\u003eToolbox lid\u003c\/li\u003e\n  \u003cli\u003eGarage wall or man cave display\u003c\/li\u003e\n  \u003cli\u003eCar trailer interior\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c!-- COMPLETE KIT --\u003e\n\u003ch3\u003eComplete Kit — Everything Included\u003c\/h3\u003e\n\u003cul style=\"list-style:none; padding-left:0;\"\u003e\n  \u003cli\u003e✅ Mad4Metal Buick Nailhead Hilborn Injected Billet Aluminum Badge\u003c\/li\u003e\n  \u003cli\u003e✅ 2x 1\/4\"-28 Stainless Steel Pan Head Screws (18-8 SS)\u003c\/li\u003e\n  \u003cli\u003e✅ 2x 1\/4\"-28 Nylon Lock Nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c!-- SPECS TABLE --\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse; font-size:14px;\"\u003e\n  \u003ctbody\u003e\n    \u003ctr style=\"background-color:#f5f5f5;\"\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold; width:45%;\"\u003eMaterial\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e6061-T6 Aircraft Grade Billet Aluminum\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eFinish\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003ePolished — machined surface marks visible (intentional character)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f5f5f5;\"\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eHeight\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e2\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eWidth\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e3\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f5f5f5;\"\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eThickness\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e3\/16\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eBolt Hole Spacing (center to center)\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e2-3\/8\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f5f5f5;\"\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eFastener Thread\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e1\/4\"-28 Fine Thread\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eFasteners Included\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e2x 18-8 Stainless Pan Head Screws + 2x Nylon Lock Nuts\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f5f5f5;\"\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eEngine Reference\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003eBuick Nailhead V8 401 \/ 425 cu in — Hilborn Injected\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003e0.9 oz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color:#f5f5f5;\"\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd; font-weight:bold;\"\u003eMade In\u003c\/td\u003e\n      \u003ctd style=\"padding:8px 12px; border:1px solid #ddd;\"\u003eUSA 🇺🇸\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003c!-- WHY MACHINED ALUMINUM BEATS EVERYTHING ELSE --\u003e\n\u003ch3\u003eWhy Machined Aluminum Beats Everything Else\u003c\/h3\u003e\n\u003cp\u003eCast zinc cracks under vibration. Plastic fades and chalks with heat cycles. Stick-on emblems peel — every time, no exceptions. 6061-T6 aluminum doesn't do any of those things. It's the same alloy used throughout the aerospace industry: light, strong, corrosion-resistant, and completely indifferent to temperature swings. When the finish dulls, you polish it back. No repainting, no replacing, no starting over. A Nailhead with Hilborn injection deserves hardware that takes the craft as seriously as the build does.\u003c\/p\u003e\n\n\u003c!-- MADE IN USA CLOSING --\u003e\n\u003ch3\u003eMade in the USA — Coeur d'Alene, Idaho\u003c\/h3\u003e\n\u003cp\u003eMad4Metal is a brand of Jacer Enterprises, LLC, operating out of Coeur d'Alene, Idaho.
