Buick Nailhead Shorty Header Set Uncoated
The BNH1 is one of our latest designs in a series of headers for "nostalgia" engines. The letters "BNH" stand for "Buick Nailhead", the venerable Buick V8 engine that powered numerous dragsters, lakesters, and hot rods in the sixties and seventies. A build-up series by Doc Frohmader in Street Rodder Magazine has sparked a renewed interest in the might 401/425 engines.
The BNH1 header fits all street rod chassis, pickups, and customs without a cross member under the center of the engine, or steering interference just behind center of the engine.
Comes with all hardware necessary for installation.
