Ford’s 5.0L V8 PFDI engine combines several features and technologies to help provide outstanding performance. Plasma transferred wire arc (PTWA) “spray bore” technology replaces cylinder sleeves to help reduce cylinder block weight. Cylinder head casting with high-flow ports provides a straight path to the valves for less restrictive intake and exhaust flow.

Ford’s 6.7L Diesel engine is designed to handle a mixture of up to 20% biodiesel by volume and 80% petroleum diesel fuel. Compacted graphite iron (CGI) deep-skirt engine block and aluminum cylinder heads help reduce weight while maintaining maximum strength for the horsepower and torque capacity of the Power Stroke V8.

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.
