Torque Specs for a 5 0 Liter Mustang Cylinder Heads

Ford debuted its Mustang in 1965. Just three years later, it introduced a new engine, the so-called 302, or 5.0 liter V8 engine, a member of Fords Windsor engine family. This performance-oriented engine was available until the end of the 1970s.

History

Ford introduced the 5.0 liter, or 302-cubic-inch, engine in 1968 in anticipation of emissions standards established by the federal government in the 1970s. It remained an available engine in the Mustang until 1973. It was reinstated in 1975 and ended its run in Mustangs in 1979.

Cylinder Head to Engine Block

The bolts joining the cylinder head and the engine block require three distinct applications of torque executed in a helical sequence. The bolts require first 45 foot-pounds of torque, then 55 foot-pounds and finally 70 foot-pounds of torque. You should wait about 15 minutes between each step to allow the bolts to settle and stretch.

Other Specifications

The intake manifold bolts to the cylinder head in three stages: first to 12 foot-pounds, second to 20 foot-pounds, and third to 22 foot-pounds of torque. In 5.0 liter engines manufactured in 1969 and 1970, the rocker arm stud bolts to the cylinder head with 70 foot-pounds of torque. The valve cover bolts to the cylinder head with 4 foot-pounds of torque.
