Cadillac 331 (Early) Exhaust Flange

$45.00

Includes one pair of exhaust flanges for the Cadillac 331 (early, small port heads) 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 and a surface ready to weld to.

 

Motor Application:

Cadillac

            331 cu. in (1949-51)

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

 

Ports designed to be used with 1-1/2″ (end ports) and 1-3/4″ (center port) exhaust tubing.

 

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