In a recent video on the MotorTrend YouTube channel, John McGann and the Car Craft team finished up a very cool 1972 Nova build. At first glance, it looks like a clean but not especially unusual Nova, but there's something interesting under its hood. Rather than a classic 350ci small block or even an LS V8, this Nova is powered by the new GM 6.6L L8T engine typically found in Silverado 2500HD and 3500HD trucks.
