Holley's high-mount base accessory drive kits have everything pulled up and in tighter than other options. The patent-pending accessory drive incorporates the timing cover, water pump, and alternator and can also be configured with A/C and/or P/S if desired. The systems are designed to work with the factory crank pulley, as well as aftermarket damper and pulleys. Accessory drive components in the system can be configured in several different ways. For example, there are alternator options offered for different performance and electrical demands. Also, deleting the A/C and/or P/S are options. These "base kits" supply all but the components with options. If you purchase a "Holley complete kit," all these options are already chosen for the most common, cost-effective combination. Features and benefits: * Fits Ford 7.3-liter Godzilla engine—ideal for engine swaps * Provides additional accessory clearance for swap applications that work with the factory rear sump oil pan * Allows for A/C and/or P/S delete and choice of alternator * Includes new front main seal and installation tool * Works with the original factory crank pulley, as well as aftermarket damper/pulleys * Alternator options do not require the original ECU control to function * P/S pump with the optional external reservoir is ideal for hydro-boost applications * Choose from natural "as-cast" or black finish on the timing cover

Holley Dominator billet fuel pumps feature a patent-pending twin-pump design. It allows you to use one pump for cruising and both pumps when you activate the nitrous switch or start building boost. By staging the second pump, you eliminate the unnecessary recirculation and heating of extra fuel, which can lead to poor performance and hot fuel issues. They can also be wired for full-time duty to get the maximum performance and are proven with an 18 V compatibility at pressures of up to 80 psi. At only 5.1 lbs., they weigh half a pound less than other 1,000 hp pumps, and yet they have twice the features. Features include: * Billet aluminum construction with anodized finish * -10 AN O-ring inlet/outlet for high flow and superior sealing * Excellent for use with carburetor or EFI applications * Compact for easy installation on frame rails or other tight spaces * Proven durability beyond 3,000 hours in gasoline or diesel fuels * Fully sealed, can be submersed if necessary
