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.

Note: These manifolds are not legal for sale or use on any pollution-controlled motor vehicles.
