Dodge A Series 277-326 Exhaust Flange


Includes one pair of exhaust flanges 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.

    Andy, Please consider making a Poly exhaust flange adapter to accept the LS or HEMI block hugger headers. It has been done (you could now garner these sales and I would promote your product on Mopar network) and is quite simple.
    Thank you, Gary

    Thanks to Andy at Hells Gates Hot Rods one of Mopars forgotten but very powerful engines can breathe new life with these nicely manufactured exhaust flanges. Custom headers are a breeze to weld with new thick Poly 318 flanges.

    Thank you for keeping the Mopar flame lit!
