Trick Flow® R-Series intake manifolds for small block fords are designed for maximum power delivery on heavily modified street/strip and race engines that operate in the 3,500-7,500+ rpm range--right where it's needed the most. Vital features include A319 aluminum construction, integral bosses for nitrous or fuel injection nozzles, and extra material for custom port work. These carb-style EFI manifolds accept standard Bosch or Siemens-type fuel injectors. Overall height to the mounting pad is 6.300 in. (5.0L/302) or 6.450 in. (351 Windsor).
