Chevrolet Small Block 262-400 (Rectangle Port) Exhaust Flange

Includes one pair of exhaust flanges for the Small Block Chevrolet 262-400 hot rod engine (see engine applications below).  These flanges are cut with a fiber laser 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 then a light coated lightly with oil.  The end result is less work to clean off the mill scale as needed with hot rolled mild steel.
