Buick Straight 8 248-263 Exhaust Flange


Includes one pair of exhaust flanges for the Buick Straight 8 248, 263 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.  The end result is less work to clean off the mill scale as needed with hot rolled mild steel.


Motor Application:

Buick Straight 8

            248 cu. in (1934-50)

            263 cu in (1950-53)

            *more applications/years may work, verify before purchasing.


Ports designed to be used with 1 1/2” exhaust tubing.


These flanges are designed in CAD and are test fit to make sure proper fitment is achieved.
