Noted speakers Steve Tanzi of Erson Cams and Darin Morgan of Profiler Performance will moderate an open discussion about cylinder head airflow and camshaft performance. Morgan and Tanzi will focus the discussion around how cylinder heads are affected by camshaft lift and duration and other factors that influence today’s racing heads and cams.
Darin Morgan has been porting cylinder heads for well over 20 years. He has specialized in Pro Stock cylinder heads since 1991 but his expertise in induction research and development is far reaching.
