Ford FE fans know that when it comes to building a Ford FE engine, nostalgia and horsepower go hand-in-hand. One classic manifold that has never gone out of style is the rare Tunnel Wedge intake. It was a landmark design 50 years ago, but Trick Flow knew that with some modern ingenuity and manufacturing know-how they could make it even better. So Trick Flow’s high performance engineers went to work and the R-Series Tunnel Wedge Intake Manifold for Ford 390-428 was born.

Part of the original Tunnel Wedge’s cool factor was its appearance, so Trick Flow took special care to match the looks of the legendary OEM version while maintaining the original carburetor locations. On the inside, Trick Flow made noticeable improvements to the port design while also incorporating a much-needed O-ringed sealed bottom plate. Cast in premium grade A319 aluminum, the manifold is topped with carb flanges machined for original Ford FE Tunnel Wedge-type square bore carburetors. Mounting hardware is included.
