Double Shot in a Ford Flathead Powered Dragster

The frame's long enough, so why not load it with tandem 8BA Ford flatheads, displacing 284 ci apiece and making something like 1,000 hp. Flathead wiz Tony Lloyd built this pair, using Ross pistons and Crower forged steel rods. The billet stroker cranks are right out of the Flathead Jack catalog, as are valvetrain components under Offy heads, controlled by custom-ground Potvin eliminator cams. Hilborn fuel injection feeds nitromethane fuel to the engines. The Lenco two-speed racing transmission is matched with a Hays double-disc slider clutch. The dual blocks had to be lined up perfectly. Machinist Gene Batteux created couplers to connect the rear flywheel flange of the front crankshaft to the snout of the rear crankshaft. Front to back, the length of the engines is 48 inches.

Next to the double flatheads, the most eye-catching thing about Flathead Jack's dragster is the great-looking body. Greg Westbury from Westbury Hot Rods in Concord, CA, handbuilt it from 0.040-inch aluminum. Westbury also did a lot of work on Jack's custom Merc, which can be seen on the Flathead Jack Web site. Once the sheetmetal work was done, legendary hot rod painter Art Himsl, also from Concord, stepped in to finish the body with the world's longest scallops. The lettering was hand-painted by Basil Platt and cleared.

The elaborate tube chassis was fabricated by chassis builder and racer Pete Ogden, who continued the theme of modern performance and old style. The components on the frame provide all necessary safety and performance components and still maintain a nostalgic style, including the long, narrow front end typical of the old slingshot-style rails.

The frontend was built with parts from SPE Speed Products including Anglia-type spindles. The custom-built 9-inch rearend and rear brakes are from Strange Engineering. The drag parachute is a Simpson Crossform. In bare form, the chassis weighs 144 pounds.

The safety and styling combination extends into the cockpit, where the high-back seat is an improvement on the cars of the '60s. Style comes from the black Naugahyde, stitched up by Howdy Ledbetter from Fremont, CA, in a diamond pattern Flathead Jack says is reminiscent of early Tony Nancy cars.

The rear wheels are 15x10 five-bolt Convo Pro/Drag Racing Centerlines, wearing 30-inch Goodyear Eagle slicks. Front wires from Spitzer Enterprises roll 22.0x2.5-17 Goodyear Top Fuel Front Runner Eagles. The wheelbase is 185 inches.

As a final touch, Art Himsl took his brush to the nose of the dragster to add the ominous Professor Fate skull and crossbones.
