Old school looks, modern performance, and advanced manufacturing all rolled into one—Trick Flow's® R-Series Tunnel Wedge intake manifold for Ford 390-428 delivers just that. 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 improving upon its performance. Trick Flow® was able to maintain the original carburetor locations—but on the inside of the manifold, Trick Flow® overhauled the port design for more airflow and incorporated a new O-ring sealed bottom plate. Cast in premium-grade A319 aluminum, the manifold is topped with carb flanges machined for original Ford FE Tunnel Wedge-style square bore carburetors. Mounting hardware is included.
