The 2015 Ford Mustang V8 has been improved from lessons learnt developing the special edition 2013 Ford Mustang Boss 302.
The alterations include:
- Larger intake valves
- Larger exhaust valves
- Revised intake camshafts
- Revised exhaust camshafts
- Stiffer valve springs
- Improved cylinder head ports
- Larger valves
- Lighter and more durable rods
- Rebalanced forged crankshaft
Along with the internal changes, the intake manifold has been adapted to allow for partially closed port flow at lower engine speeds. This will improve air-fuel mixture and economy, idle stability and emissions.
These changes should bring around 420 horsepower and 390 lb.-ft of torque, a similar rating to the 2013-2014 Ford Mustang GT.
