The 427 FE was one of Ford’s great competition big-blocks. Its Side-Oiler architecture fed the crankshaft main bearings through a dedicated oil gallery, helping durability at racing loads.
Street and race specifications varied substantially. The often-quoted 425 hp figure applies to certain street dual-four-barrel versions under SAE gross, not every 427.
The 427 FE became closely linked to Ford’s Le Mans-winning GT40s and NASCAR efforts. It must not be confused with the longer-stroke 428 Cobra Jet.
