54022 Power+Plus Small Block Ford 351W Typhoon Aluminum Intake Manifold Polished

Polished finish. The Power+Plus Typhoon manifold for 351W engines is the ultimate street performance manifold for this engine. It provides good top end power without sacrificing bottom end torque. Its long runner dual plane design provides the best of both worlds. Best with an aggressive street cam. For street, use a 600-750 cfm vacuum secondary or double pumper carb. For competition, use a 750-850 cfm double pumper. This manifold has a number of features not found in similar competitive manifolds. It includes a rear water crossover passage which can provide for more balanced cylinder head temperatures and a cooler running engine. It also has correctly positioned nitrous bosses for those of you who would like to add port nitrous injectors to your engine.
