An aluminum block compared to its iron counterpart transfers heat better and weighs 100 lbs. less. While weight reduction is helpful to drag racers, it's huge in road race and autocross for its effect on vehicle turning and braking. This block also brings a six-bolt head bolt design and the strength to easily handle this power level.
