hay ray my father had a prince skyline GT in 66 then updated again in 67 with another GT . this was a factory tripple webber carb small cubic inch inline 6 that was backed by a 5 speed manual trans. back in 67 the v8 was just thinking of getting on the scene here in australia and the next thing on the quick list was the mini cooper S . i would have to ask him for the engine specs but i think it was pretty slick for its day..
