Includes one pair of exhaust flanges for the Chevrolet 348, 409 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:
Chevrolet V8
348 cu. in (1958-61)
409 cu in (1961-65)
*more applications/years may work, verify before purchasing.
Ports designed to be used with 2” OD for the exhaust ports.
These flanges are designed in CAD and are test fit to make sure proper fitment is achieved.
