Ford’s FE and 385-series big block engines have become increasingly popular in the classic truck community thanks to renewed support from the aftermarket. Found powering everything from the iconic Le Mans-winning GT40 Mk IIs and NASCAR Ford Galaxies to passenger cars and F-Series pickups, Ford’s big block motors are abundant, easy to find and are known for their ability to create lots of ground-pounding torque. Now, Hedman Hedders has developed two all-new headers that allow owners of 1954-1972 Ford F-100s to easily swap these torque monsters into their classic trucks.
Hedman’s new swap headers for the F-100 are engineered to deliver maximum exhaust flow while maintaining a lower profile than traditional long tubes. Available as a mid-length header for the 352-427 cubic inch FE-series motors and as a short tube header for the 429 and 460 cubic inch 385-series motors, these headers feature 1 ¾-inch mandrel bent primaries and 3-inch collectors – giving them the capacity to complement any of Ford’s heavy breathing big block engines with ease. These headers also feature Hedman’s integrated ball-and-socket style flange collector to provide a durable, gasket-free seal.
Built in the U.S.A., Hedman’s swap headers for both FE and 385 series engines are constructed with 5/16-inch flanges to keep the 16-gauge primary tubes firmly attached to the engine even under harsh driving conditions. These headers are available in your choice of either an uncoated finish (Part# 89130 and 89230) or a silver HTC high-temp ceramic-metallic coating (Part# 89136 and 89236) and are available for 352, 390, 427, and 428 cubic inch FE engines and 429 and 460 cubic inch 385-series engines with factory-style heads.
Mounting hardware, gaskets and installation instructions are also included with the headers for a pain-free installation. These headers are built so well that Hedman guarantees them for life and the HTC-coating for five years.
