Chevrolet 4.3L V6 (1.625″ Port) Exhaust Flange

Includes one pair of exhaust flanges for the Chevrolet V6 4.3L engine (see engine applications below).  These flanges are cut with a CNC 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 and then coated lightly with oil.  The end result is a surface ready to weld to without the extra prep time to remove mill scale. 

Engine Application:

            4.3L, 262 cu. in (1985-95)

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

These flanges are designed in CAD and are test fit on an actual head to achieve proper fitment.
