See Emissions Details
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 & right side-mounted starters) and provide clearance for several automatic & manual transmission options. Manifold fitment has been confirmed on the following Gen III 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 III 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 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

This product is engineered to facilitate the installation of a later model, emissions friendly engine into a vintage / classic vehicle. Federal guidelines indicate that an engine swap is allowable if one or more of the following conditions apply:

  • If there is a reasonable basis for knowing that emissions are not adversely affected as described in the EPA Tampering Policy dated November 23rd, 2020
  • The resulting vehicle is identical (with regard to all emissions related parts, engine design parameters and engine calibrations) to a certified configuration of the same or newer model year as the vehicle chassis
  • The vehicle is a uncontrolled vehicle - Vehicles that were manufactured before emission control regulations took effect are called uncontrolled vehicles. Aftermarket parts regulations and anti-tampering laws do not apply to these vehicles
  • An EO legal engine swap kit is utilized (such as a GM EROD)
  • The vehicle is being used for Competition Use Only - Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street

Consumers are responsible for complying with laws prohibiting tampering, and for ensuring that modified vehicles are operated in a manner that complies with applicable laws.

Motor vehicle emissions standards are intended to help achieve and maintain air quality goals that benefit human health and the environment. The U.S. Environmental Protection Agency, the California Air Resources Board, Environment Canada, and other regulatory agencies prohibit the operation of vehicles on public roads that violate applicable emissions standards. The alteration of certified production vehicles to modify, remove, or render inoperable emissions control hardware or software, known as "tampering" is prohibited by the U.S. Clean Air Act and other laws. Tampering with motor vehicles emissions control systems is punishable by substantial monetary penalties.

Holley is committed to performance parts that allow enthusiasts to modify their vehicles and meet emission requirements.
