Holley offers a split plenum manifold for LS engines with cathedral ports heads (LS1, LS2, LS6). Their part number is 300-255 in a natural finish and 300-255BK in a black finish. These cast intakes have a split plenum to allow easy porting for increased airflow. This video shows a 300-255 getting 5-axis CNC porting on our Rottler. Watching this machine run is always fun so enjoy and give us a call at 815-725-2727 if you'd like one of these intake manifolds for your ride. #holleyperformance #holl
