Both the 1963 pushrod and 1964 DOHC Ford engines were 255 cubic inches. During that period of time the Offy's were also 255. Later in the 1960's pushrod motors could run at 305 which is what Dan Gurney did with his Weslake headed Fords. In 1968 when they started turbocharging the engines the size limit became 2.65 Liters. Bobby Unser won with the Offy when the two turbines died with 10 laps to go.
