World Products Merlin-X Manifolds

Product images may differ from actual product appearance.

Due to the increasing popularity of large displacement big block Chevy engines, the engineering team at World Products has developed these new Merlin-X intake manifold especially for 509 and greater cubic inch BBC applications. What's more, these manifolds have been designed expressly for use with large 4500-series Dominator-style carburetors. Extensive flow bench and dynamometer testing has shown them to provide excellent performance throughout a wide rpm range. While the Merlin-X's are single plane manifolds, their plenum dividers and other design features give them the kind of throttle response normally attributed to dual-plane intakes. In many larger c.i.d. applications, they've proven to out-perform top of the line cast manifolds from other manufacturers.
