The 427 engine produces a tremendous 590 horsepower at 6,500 rpm and 509 foot-pounds of torque at 5500 rpm. Remarkably, the engine is almost 70 pounds lighter than the 5.4-liter 32-valve Cobra R engine from the Ford Mustang. The 427 achieves this astonishing power-to-weight ratio through the following attributes:
* Siamese bore aluminum V-10 engine block based on Ford's modular V-8 DOHC engines
* Ford-pioneered metal spray process to maximize the bore at 95mm
* Newly designed lightweight forged aluminum pistons with a very short compression height
* Aluminum cylinder head derived from the SVT Cobra R Mustang
* New billet H-beam connecting rods and billet steel common pin crankshaft for increased strength without the need for a balance shaft
* Lightweight hollow stem valves
