PowerFlow B/B (Polished Manifolds Only) 

Polished Big Block Manifolds

Polished big block manifolds. (Sold in pairs)

These high performance manifolds are unique in design, that creates a high velocity airflow that increases torque, rpm, and horsepower over stock cast iron manifolds on big blocks. We have experienced 40 to 50 foot pounds of torque on big block 502, 415 horsepower motors, and 80 to 90 foot pounds of torque on engines up to 575 cubic inches.

Powerflow manifolds are water-jacketed, water surrounds each exhaust passage, including the ports to eliminate burnout. Black manifolds are hard anodized prior to powder coat, to ensure against corrosion. All manifolds are available in Recirc or standard.

The risers are highly polished stainless steel, and are designed for 4" exhaust tips. We offer a wide variety of riser pipe configurations (AS SHOWEN IN RISER PIPE SECTION), to accommodate just about every application. Custom riser pipes can also be manufactured to order, just give us a call for details.

Our Powerflow manifolds have a weight savings of 80 pounds over stock cast iron big block manifolds. It allows for twin engine mounting down to 33" centers.
