Ford Small Block 221-351W Straight Lake Header Kit

$150.00

Includes One Straight Lake Header Kit for the Small Block Ford 221, 260, 289, 302, 351W 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 lightly coated with oil.  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 (Include in order notes)

1 – 1-5/8″ OD, 0.065″ wall plain steel (not aluminized!) 180 degree mandrel bends
