1. The graph illustrates that the Brodix heads did more than just increase the peak power output. Making more peak power is always welcome, but making more power everywhere is the sign of a well-designed cylinder head. The Brodix heads increased both peak power (from 744-799 hp) but also peak torque substantially (682-714 lb-ft). The fact that the impressive airflow came with no change in intake port volume indicates that these Brodix heads will be equally at home on a stock-displacement 427 LS7.
