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, see below. 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, and 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. 1967-1972 A-Body manual steering only, requires power steering or shortened steering column tube and u-joint style coupler 1966-1972 B-Body-Manual or Power Steering, Figure 3 in photo & instruction sheet 1970-1974 E-Body-Manual or Power Steering, Figure 3 in photo & instruction sheet 1987-1996 Dodge Dakota 2wd V6/V8 1997-2004 Dodge Dakota 2wd V6/V8-Upper Control arm clearance recommended, Figure 4 in photo & instruction sheet 1972-1993 Dodge D100/D150
