Mopar Small Block 318-360 Swept Lake Header Kit

$175.00

Includes One Swept Lake Header Kit for the Small Block Mopar 318, 340, 360 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)

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

    Bought this kit to make a set of twin turbo headers, really nice clean bends and welds. Header flanges are really clean cut and fit perfectly. I’m looking forward to working with such clean material. Hells Gate Hot Rods went out of their way to get what I needed for this job. I’m definitely a repeat customer!!!
    Thanks Danny

    Great communication let me now bends where on back order and would be not over two weeks.The were sent in the stated time. Great material. Only thing the mounting flang was square bore and the pipes ends round which is clearly show, however would be nice if they offered a adapter flang as some company’s due. I would order another set from this company.
