Ford GT MK IV J4 - 1967 12 Hours of Sebring Winner Museum Display Sign

This is a photograph of a yellow museum display placard describing the Ford GT MK IV, chassis J4, winner of the 1967 12 Hours of Sebring as a Ford team car. The sign lists key specifications: a Ford 427 cid engine producing 525 h.p. and a top speed of 225+ M.P.H., with the car owned by Larry Miller. A period photo on the placard shows the white #1 GT in the pits at a race. The descriptive text explains that Henry Ford's decision to defend Ford's 1966 successes at Daytona, Sebring and Le Mans drove development of an all-new car, since the MK II GT-40 (based on the steel-chassied 225 c.i. MK I) had reached its developmental limits. The MK IV was a technologically advanced endurance racer built entirely in the U.S., constructed of 1" and ½" aluminum honeycomb panels with a basic chassis weighing only 85 lbs, the first car to use this now-common material, achieving a weight saving of nearly 300 lbs. Other innovations included wheels designed to pump hot air out of the brake calipers. The final paragraph, noting J4 was the first MK IV built and its Sebring win, is cut off at the bottom of the photo.
