239CI FORD FLATHEAD V8: MILL OF THE MONTH

1935 Ford Cabriolet with 239ci Ford Flathead V8

Feast your eyes on some hot-rodding porn – it’s 239 cubes of injected flathead fury heading for a cool 1935 Ford Cabriolet belonging to Sydney hot-rodder Geoff Oppy.

“When I built my rod I knew it had to have a flathead,” Geoff says. “I went to the States and looked at a lot of hot rods; none of them had a motor like this.”

The engine itself was built around 12 years ago, but was never fired up until recently. So Geoff had flathead guru Eric Worner pull the engine down and give it a tidy-up before it was re-assembled and fired up.

“I paid $40 for one and $80 for the other,” he says. “They were only used in Canada, same as the alloy timing cover I bought on eBay.”

“I didn’t like the stacks that came with it so I made my own and topped them with gauze filters,” Geoff says. The Bosch injectors and Delco ECU were sourced from a non-Ford – Geoff doesn’t want to talk about what they’re actually from – and the ignition is an electronic Mallory distributor.

“I don’t know,” Geoff says. “Not a great deal; it’s more of a show and nostalgia thing.”  S

WHAT’S A FLATHEAD?

Flathead motors are so named because, well, their heads are flat. There’s no valve gear or moving parts in the cylinder heads; the valves are in the block. Ford Flathead V8s were used from 1932 to 1953 in the USA
