A great choice for street and strip, boost or naturally aspirated carbureted LS swap vehicles, this is Holley's mid-rise carburetor intake for GM LS3/L92 motors. Please note, this is for square port cylinder heads and *will not fit* Cathedral port cylinder heads (such as LS1, LQ4). For cathedral port intakes, please see our other items.

This is a great choice for those using the GMP CNC ported (or unported) heads on their 6.0 and larger motors.
