The Speedmaster LowRise Manifolds are our lowest profile manifold and is also the only one that is street legal on pollution controlled vehicles. It is set up to accept a spread bore carb but comes with an adapter plate that permits the use of square bore carbs. To remain street legal with a square bore carb, you must use one that is also approved as street legal for your application.

This Speedmaster LowRise 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. Remember that every Speedmaster manifold is 100% pressure tested to discover any air, water, or exhaust leaks before you install it on your engine.
