Brand new castings of the original 1970, 1971, 1972 W30 exhaust manifolds W and Z. They were also used on 1969 big blocks, the only difference was that in 1969 the left manifold had a heat riser. Highly detailed for show quality restorations. LH manifold "W", part #402295. RH manifold "Z", part #402294. Will fit Oldsmobile big block 400, 425 and 455 A body cars 1965-1972.
