Tuhia he haere tonu mo tenei waahanga - I mahi tahi a Shelby American me Ford ki te whakahou i te GT40 mo te wa o te '66, ka whakakapi i te miihini 289 inihi kapi (4.7 L) ki te Ford nui ake, kaha ake 427 cu. in. (7.0 L) pūkaha. I angitu te Mk II GT40, me nga wikitoria a Shelby American i Daytona, Sebring me Le Mans i whiwhi ai a Ford i te Tohu Kaihanga o te Ao i te tau 1966. Ko nga motuka Shelby American i mutu tuatahi (Miles & Ruby ano) me te tuarua (Gurney & Jerry Grant) i Daytona, tuatahi i Sebring (Miles & Ruby), tuatahi (McLaren & Chris Amon) me te tuarua (Miles & Denny Hulme) i Le Mans
He aha? Ko Gurney rāua ko Grant i mutu tuarua i Sebring, engari i pakaru to rāua waka i te poro whakamutunga, ā, i pana a Gurney i te raina mutunga, nā reira i kore ai rāua e āhei.
