Ford 7.3L PFI Engine
Ford’s 7.3L PFI gas V8 engine is newly designed and built from the ground up. This engine implements the same anti-wear materials as Ford’s turbocharged applications, adding more long-term strength. Its pushrod design has two valves per cylinder, with pushrods allowing for a more compact design, and roller valve actuation offering greater efficiency. This engine is smaller, lighter, provides more torque and hp, plus better fuel economy than its 6.8L predecessor.
