The popular 200-c.i.d. six-cylinder engine is the standard power plant for all Mustangs except the Mach 1 Model. In offering a maximum choice in total equipment, however, two new engines have been produced for 1969 and are included in the Mustang lineup.
The 4.1 Litre (250 c.i.d.) six-cylinder engine is designed to develop nearly 35% greater horsepower than the standard six . . .at the same time is almost as economical in fuel consumption.
The 351-c.i.d. 2v V-8 is standard in the mach 1 and this desplacement is available as an option in either two-barrel or four-barrel versions on all other Mustangs. It is extremely compact, lightweight and provides excellent performance and handling characteristics. The lower vegicle weights results in greater acceleration.
The 428-c.i.d. 4v V-8 engine is Mustang's latest entry for the performance car package. It is also available in a Cobra Jet "Ram-Air" version on all Mustang models.
