Flowtech Headers are the perfect combination of quality and value. These Tri-Y style headers fit the popular 1965-1970 Ford 260/289/302 V8 engines. These Tri-Y style headers were originally designed for 1965-1966 Shelby GT350 Mustangs with a 289HiPo V8, 4-speed manual transmission, and manual steering. Over the years, Ford enthusiasts have used these headers in dozens of other vehicles to get that classic Shelby sound and performance. See Installation Notes for additional information regarding fitment details regarding these headers.
