I know Ford has 13 Ford GTs on the grid at LeMans in '66, but Ferrari probably only had 3 or 4 prototyppes that could run toe to toe with the big block Fords. Have any Ferrari historians speculated in print why Ferrari didn't pull out of F1 and all other racing as early as '64 or as ;ate as '66 in order to be able to field a dozen mid-engined GT prototypes at LeMans? Didn't Enzo realize losing to Ford. a maker of mundane passenger cars--would hurt Ferrari's hard won image and allure? My pet theory is that Enzo never thought a cast iron block cast iron heads pushrod V8 could beat his sophisticated V12s. Or maybe he thought a self taught failed chicken farmer like Shelby coun't steer Ford in the direction they needed to go?
