Hooker Blackheart Gen 3 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 & right side-mounted starters) and provide clearance for several automatic & manual transmission options.
Manifold fitment has been confirmed on the following Gen 3 Hemi swap vehicles when used with Holley engine swap components: Compatibility with other vehicle combinations and swap components is likely but has not been confirmed.
1966-1972 B-Body - manual steering ONLY, reduced head cover bolt recommended; see Figure 3 on Instruction Sheet
1970-1974 E-Body - manual steering ONLY, reduced head cover bolt recommended; see Figure 3 on Instruction Sheet
1987-1996 Dodge Dakota 2WD V6/V8
1997-2004 Dodge Dakota 2WD V6/V8 - Upper Control arm clearance recommended; see Figure 4 on Instruction Sheet
1972-1993 Dodge D100/D150 - automatic transmission ONLY
Features:
- Gen 3 Hemi swap exhaust manifolds – a compact, High Flow design with a factory look that is ideal for engine swaps with limited space
- Choose from plain as-cast, black ceramic, or silver ceramic finishes – ceramic finish reduces underhood heat and resists corrosion
- Intended for Gen 3 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
