Designed for 289-302 c.i.d. Ford V8's. This manifold offers excellent performance as well as a hot looking package. With two Edelbrock carbs in-line, progressive throttle linkage and braided fuel line, this low-profile design allows adequate hood clearance and maintains great driveability. Mounting bosses for throttle cable brackets make the F-28 suitable for late-model applications. Carb center to carb center is 6-7/16. Use Performer-Plus cam #2122 for low-end torque or Torker-Plus cam #5022 for top-end power. See accessories section for chrome, Elite and Classic Series oval air cleaners for a great looking package.
