AFR's New 165cc Renegade Heads - Airflow Redefined

We install and test AFR's new 165cc Renegade heads.The small-block Ford cylinder head market is flooded with options ranging from 160cc intake runners all the way to huge 240cc high-port race heads and everything in between. But bigger is not always better, especially for a street-driven Stang. The size of the intake runner dictates air velocity, and the smaller displacement an engine has, the less velocity the incoming air will have when using larger intake runner cylinder heads, especially at low rpm.
