2007.5-2010 Duramax Race Long Block (PDM-LMMRLB)

Description

The Industrial Injection Race Long Block is built for those pushing the 6.6L Duramax LMM to the limits of performance. Each long block combines a fully built bottom end with 5-axis CNC race-ported heads, designed for reliability under competition use.
