HAISLEY MACHINE’S NEW 24-VALVE SUPER STOCK CUMMINS

Haisley Machine brought one heck of a conversation piece to PRI, and parked it front and center at the ARP booth. Interestingly enough, the company’s latest Super Stock mill, a deck-plated Cummins with a billet 18mm pump from Wimer Fuel Injection & Turbo, featured a 24-valve cylinder head. A sleeved, factory-based 6.7L block still seems to be part of Haisley’s recipe, along with triple turbos, water injection, and a 4-disc clutch. Other highlights for the 3,000-plus horsepower Cummins include SMT’S roller rocker system, a 4-core waterto-air intercooler from Sandridge Customs, Custom Floater bellhousing, and a Profab Machine reverser.
