With all due respect, my mates down under have an excuse for running Chevrolet engines: that's what's available. Not that I have anything against Chevvies, my current daily driver is my fifth Corvette, a '96. And if my trusty bow tie blows up while I'm autocrossing it or something, an LS3 sounds like a great replacement. And while my Shelby engine in my Cobra isn't a "real" Ford motor, it *is* a good replica, like my Cobra itself. Yeah, call me a "purist" or old fashioned if you will. In car shows I even seek out '32 Fords with flathead engines and Edelbrock heads, Stromberg 97s, Belond headers, etc. Ah, the good ole days!
