Hooker BHS558 Blackheart Gen 3 Hemi Swap Exhaust Manifolds, Raw

Hooker Blackheart Gen III Hemi swap exhaust manifolds are one part of a fully engineered swap system that provides maximum component clearances and ideal drivetrain geometry. These manifolds are designed to fit a wide range of swap applications where clearance is limited. Fitment has been confirmed on several popular platforms, including 1987-2004 2WD Dakota, 1972-1993 2WD D100/D150, 1966-1972 B-body with manual steering box, and 1970-1974 Mopar E-Body with manual steering box when using the Holley swap system components.

These exhaust manifolds are cast from hi-silicon-moly ductile iron and feature 2.5-inch 2-bolt collectors. These manifolds provide clearance to the brake booster, steering shaft, steering box, starter motor (both left And right side-mounted starters) and provide clearance for several automatic And manual transmission options.

• Gen III Hemi swap exhaust manifolds – a compact, High Flow design with a factory look that is ideal for engine swaps with limited space
• Plain as-cast finish
• Intended for Gen III Hemi engine swap applications where durability, quiet operation, and leak-free sealing are desired
• Cast from heavy-duty hi-silicon-moly ductile iron for long-lasting durability and corrosion resistance
• 2.5-inch outlet diameter offers improved flow for maximum performance from cast iron exhaust manifold
• Includes collector flanges, Multi-Layer stainless Steel (MLS) collector gaskets, and bolts – that make it easy to fabricate downpipes
• Works with left or right-hand side starters and all popular transmissions
• The slotted bottom row of holes makes it easy to install (on pre-installed lower bolts and gasket for each cylinder head)
• Ideal for use in applications that require catalytic convertors
