Commonly referred to as the “Cammer” or “SOHC (pronounced sock) motor”, the single overhead cam 427 was Ford’s answer to Chrysler’s 426 Hemi in the mid-1960’s. The boys in Highland Park were clobbering the competition in the ranks of Nascar and drag racing, and for the boys in blue, who were promoting an era of “Total Performance”, it was an intolerable beating that couldn’t go unanswered. Amazingly, Ford fired back with a knockout blow of their own in a mere 90 days.
Based on Ford’s FE block design, the SOHC 427 featured hemispherical combustion chambers and free-flowing cylinder heads that housed one camshaft per bank, which were driven by six feet of timing chain hidden behind a massive sand cast cover. With a single 4-barrel carburetor, the Cammer was capable of laying down a whopping 615-hp at 7,000-rpm and 515-lbs/ft of torque at 3,800-rpm, or 657-hp at 7,500-rpm with dual 4-barrels. Later supercharged variants of the SOHC 427 powerplant were known to produce an earth shattering 1,000 to 2,000 horsepower, if not more.
Without question, it was one of the baddest powerplants ever built, producing the most power any production or race engine had ever made, easily equaling the best that the Hemi had to offer, and then some. Even though Ford managed to sell (over the counter) the required number of units to homologate the SOHC 427 for stock-car racing, changes in the rules prevented it from competing in Nascar. But not in AHRA and NHRA drag racing. After some initial development, the Cammer powered Fords quickly became formidable opponents in nearly everything from A/FX to Pro Stock competition, even Top Fuel, up through the early 70’s. Today, the SOHC 427 is respected as one of the fiercest engines ever produced, and a legend among the brigade of blue oval enthusiasts.
