Dodge A Series 277-326 Straight Lake Header Kit

$150.00

Includes One Straight Lake Header Kit for the Dodge 277, 301, 303, 313, 326, 318 Poly (A series block) 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 – please add to order notes
