According to reports, Ford has confirmed that its new 7.3-liter V-8 could fit in a Mustang or half-ton F-150, but that the engine will not be a factory option at any time.
This 7.3-liter V-8, an optional engine for the updated Super Futy series, will have a cast iron block and a forged steel crankshaft. The valves will be driven by a complete block camshaft with variable valve timing. The figures of power and torque have not been revealed, although Ford says that "this 7.3 liters is expected to be the most powerful V-8 gas of its kind." Expect more power than the 6.2-liter Super Duty base V-8, which generates 385 horsepower and 430 pound-feet of torque.
The North American product communications leader, Mike Levine, confirmed the compatibility of 7.3 with the Mustang and the F-150 for Motor authority, who also told him in no uncertain terms that the engine would not be suitable for the Mustang. Despite its high displacement and proper dimensions, Levine noted that the cast iron block of version 7.3 was too heavy for use in relatively light pony, either due to front suspension restrictions or weight distribution problems .
Reportedly, Levine expressed the certainty that the 7.3 will eventually find its way to a Mustang, though only as an aftermarket project and not as a Ford product.
Mustangs historically have had engines that approach the displacement of the 7.3, with several engines of 7.0 liters available between the model years 1967 and 1971. Since 1971, no Mustang has left the factory with an engine of more than 5.8 liters, and even the next Mustang Shelby GT500 2020 will not use more than 5.2 liters to reach its 700 horsepower more. With internal combustion engines getting smaller and smaller with the passage of time, the days of launching more trips to a problem have gone, along with the 7.0-liter Mustangs (or more, with the volume of the supercharger included).
