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...
