Over decades of thermal cycling, these heavy cast components warp and crack, causing critical exhaust leaks. Furthermore, the rough internal casting flash and sharp directional changes create severe backpressure. This restricts the 289 cubic-inch engine's ability to evacuate spent gases, resulting in elevated cylinder head temperatures, compromised mid-range torque, and significant engine bay heat soak.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eUpgrading to these shorty headers resolves factory restrictions while maintaining a compact footprint. Manufactured from mandrel-bent 304 stainless steel, the 1-5\/8\" primary tubes provide a smooth, continuous path that dramatically increases exhaust flow velocity and optimizes cylinder scavenging. Thick 3\/8\" steel flanges resist thermal warping, ensuring a permanent, leak-free seal against the exhaust ports. Terminating in 3\" collectors, they significantly reduce backpressure. Crucially, these headers clear common swap hurdles, seamlessly accommodating Ford GT-40 \"P\" heads, AOD transmissions, and factory power steering setups without requiring structural chassis modifications.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1965-1966 Ford Galaxie\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eWindsor V8 \/ 3rd Gen Full-Size\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e200 hp \/ 282 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1965-1966 Ford Galaxie with factory 289 V8 (4.7L) engine\u003c\/li\u003e\n  \u003cli\u003e1965-1966 Ford Galaxie with 260 V8 engine swap\u003c\/li\u003e\n  \u003cli\u003e1965-1966 Ford Galaxie with 302 V8 (5.0L) engine swap\u003c\/li\u003e\n  \u003cli\u003eCompatible with Ford GT-40 \"P\" cylinder heads\u003c\/li\u003e\n  \u003cli\u003eCompatible with AOD transmission swaps\u003c\/li\u003e\n  \u003cli\u003eCompatible with factory power steering configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Ford Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the rigors of high-compression combustion, these headers restore the deep, resonant exhaust pulse characteristic of the Windsor V8 while maximizing volumetric efficiency and overall horsepower.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48182510256376,"sku":"DS-E4FIL863I","price":295.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/exhaust-manifold-for-ford-galaxie-1965-1966-260-289-302-1.webp?v=1775169282","url":"https:\/\/performancechiptuning.com\/products\/exhaust-manifold-for-ford-galaxie-1965-1966-260-289-302","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
