Boosting Ford’s Cammer Big-Block
This “Mild” Ken Duttweiler-Built, Twin-Turbo, 482CI Ford SOHC Stroker Makes More Than 1,000 HP—on 91 Octane!
hOld cool: Ford’s infamous 427 single-overhead-cam (SOHC) big-block engine, the final evolution of Ford’s first-generation “FE” big-block, and perhaps one of the most outrageous examples of the classic muscle-car era’s quest for ever more power when engines were big and gas was cheap.
New cool: Taking a legendary big-block monster designed back in the 1960s and bringing it into the 21st century with electronic fuel injection (EFI), coil-on-plug ignition, and twin turbochargers.
In an effort to keep up with Chrysler’s brand-new, 426ci Generation 2 Race Hemis on the NASCAR superspeedways, in 1964, Ford decided to up the ante by modifying its high-performance, side-oiler 427 FE big-block to accept overhead-cam cylinder heads with hemispherical combustion chambers. Although around 500 crate engines were sold through Ford dealers, when Chrysler whined about unfair competition, NASCAR banned the “cammer” outright. Although it did well in drag racing, NASCAR’s ban resulted in the engine never
realizing its full potential. Still, the motor’s rarity (it was never factoryinstalled in passenger cars) resulted in it achieving a cult following.
Finding an original Cammer today outside of a museum is almost impossible, but in recent years, various niche companies have stepped up; today, it’s possible to completely build up one of these monsters from scratch using all-new parts. Car collector and hot rodding enthusiast Jim Ring was searching for the right powerplant to drop into his custom 1964 Galaxie show car when his go-to car builder, Bones Fab’s Jim “Bones” Bassett, showed him a photo of the exotic motor. “It got me excited!” Ring says. “I had to have one!”
But not just any old cammer. Ring, Basset, Lyle Larson, and legendary turbo engine builder Ken Duttweiler put their heads together and developed a plan to build a 482ci twin-turbo, stroker SOHC motor that would make at least 1,000 hp in daily-driver trim on pump gas and as much as 1,500 hp by turning up the boost and running race gas. Let’s take a closer look on how Duttweiler, Bassett, and Bassett’s Bones Fab crew melded old and new tech to build this outrageous motor.
[ Built by Ken Duttweiler, this twin-turbo, 482ci SOHC Ford V8 makes more than 1,000 hp on 91-octane gas. Hot off the engine dyno, it now finds a home in Jim Ring’s Pro Street–style 1964 Galaxie. On these pages, we’ll get into the motor’s nuts and...
