This intake manifold set features a reproduction of the factory aluminum intake manifold that came on 1971 Firebird / Trans Am cars with H/O engine. The manifold features a cast number of 483674 and has the correct ?W? snowflake logo used by Winters foundry. Set includes one aluminum intake manifold, one cast iron exhaust crossover and the correct factory two-piece crossover heat shield which insulates the intake manifold from heat produced by the crossover. It will also work on all 1965-79 Pontiac 326, 350, 389, 400, 428 and 455 engines, but is cosmetically correct for 1971 models.
Note: Manifold gasket available separately. Refer to part number# 1233.
