There’s still time to peek under the hoods of some of the most iconic and popular cars that ever rolled off an assembly line or raced down the track. An exhibition titled “Engines Exposed” runs through March 15 at the Henry Ford Museum in Dearborn, Michigan.

It’s one of the rare times that the museum has popped the hoods on 40 vehicles inside the Driving America exhibit. The last time was some five years ago, and this showing will be the first for cars like the helicopter engine in a ’48 Tucker, a 12-cylinder Flathead in a ’36 Lincoln Zephyr and the 1916 Woods Dual Hybrid Coupe, a car that was 80 years ahead of its time with an electric motor and 4-cylinder gas engine for power.

Other engines of note include a V8 Flathead in one of the George Barris’ customs and a ’33 Stutz 4-cylinder.

For race fans, there’s a supercharged Ford 427 SOHC found in Ohio George Montgomery’s ’33 Willys, the 427ci V8 from a LeMans-winning GT40, an Offy in a Meskowski IndyCar and the four injected Hemi engines in the 409-mph Goldenrod streamliner. This story in the Detroit News shows some of those engines.

Guests to the museum can get behind-the-scenes details and learn more about the engines’ details during a daily presentation in the Douglas Drive-in Theater. On March 14 at 1 pm, curator of transportation Matt Anderson will offer a glimpse at a digitized collection of engines in the theater. Throughout the exhibition there are opportunities for youngsters to learn about cars and engines through hands-on demonstrations.
