MERLIN X
BIG BLOCK CHEVROLET
SINGLE PLANE INTAKE MANIFOLDS

To provide an ample volume of air and fuel for large cubic inch engines, while maintaining good velocity was the challenge facing World's engineering team. Following extensive R&D, the new Merlin-X became a reality. It's ideally suited to 540 and larger displacement, and has proven to deliver excellent power for big 632 + inch motors! Best of all, the Merlin-X is truly versatile, and combines excellent throttle response with solid top-end power. It's designed exclusively for 4500-series (Dominator) carbs, and clearly the best all-around single plane manifold on the market for Big Block Chevy engines!
