Includes One Swept Lake Header Kit for the AMC 304, 360-401 hot rod motor (see motor applications below). These flanges are cut with a CNC HD (High Definition) Plasma cutter out of 3/8” Pickled and Oiled (P&O) steel. P&O material is hot rolled steel that has been dipped in acid to remove the mill scale and then a light coated lightly with oil to prevent rusting. The end result is less work to clean off the mill scale as needed with hot rolled mild steel.

Kit includes:

1 pair – 30″ long steel megaphones (1-5/8″ inlet & 3-1/2″ outlet) – 4″ outlet available upon request

8 – 1-3/4″ OD, 0.065″ wall plain steel (not aluminized!) 70 degree mandrel bends

1 pair – 3/8″ thick exhaust flanges – specific motor application listed above
