High Perf 330-350 Manifolds
Unfortunately there were never any factory high performance manifolds for the small block applications – even the W-31’s used the exact same crossover (capped) manifolds as the standard 350 2 barrel applications did. For those wanting to improve the performance of their 330 or 350, but not wanting to deal with the hassles and modifications required to use tube headers, we have a perfect solution! These HP cast iron manifolds are patterned after the best flowing Olds manifolds – those used on the 69-72 4-4-2 and W-30. Featuring a center divided port and a 2 ¼” outlet, these manifolds will provide a performance increase over the original style manifolds – all while giving the appearance of being factory equipment!
