Not sure which headers to use for your Windsor engine? Read our Ford Windsor header guide here.
At 4,000 rpm, a 289ci (4.7L) Windsor V8 theoretically draws in approximately 9,400 litres of intake air per minute and can expel around 28,200 litres of hot exhaust gas per minute at approximately 600°C.
At the same engine speed, a 302ci (4.95L) Windsor V8 theoretically draws in approximately 9,900 litres of intake air per minute and can expel around 29,700 litres of hot exhaust gas per minute at approximately 600°C.
A well-designed header and exhaust system helps manage this high gas flow efficiently, reducing restriction and improving exhaust scavenging, torque, throttle response and engine performance.
Pacemaker PH4010 headers are backed by Pacemaker's 2-year manufacturer warranty, subject to the manufacturer's current warranty terms and conditions.
Vehicle modifications, engine conversions and exhaust changes can affect fitment and roadworthiness. The completed installation must comply with applicable vehicle modification, exhaust noise and roadworthiness requirements.
