Ford has announced the 5.2-liter flat-plane crank V8 engine in the Shelby GT350 Mustang and Shelby GT350R Mustang is the "most power-dense and the most powerful naturally aspirated road-going engine in Ford history."

While the company has previously said the engine would produce more than 500 bhp (373 kW) and 400 lb-ft (542 Nm) of torque, the automaker has just confirmed the final output will be 526 bhp (392 kW) and 429 lb-ft (580 Nm) of torque.

Ford declined to give detailed performance specifics but confirmed the engine is also the highest-revving V8 in the company's history as it has a redline of 8,250 rpm. The automaker went on to say the engine produces "90 percent of peak torque from approximately 3,450 rpm through 7,000 rpm, and features a racetrack-friendly spread of nearly 3,000 rpm between its torque and horsepower peaks."

According to Ford Performance chief engineer Jamal Hameedi, "The high-revving, naturally aspirated 5.2-liter flat-plane V8 delivers on every target we set – high horsepower, broad torque curve, aggressive throttle response and light weight.”
