Cummins 6CT (8.3 L) Extended Long Block Diesel Engine – 300HP – 1 or 2 Thermostat Models
Our long block and extended long block assemblies are considered 'component builds'. A true component build is an engine assembly built back to popular configurations using roughly 90% OEM New Parts, 10% Aftermarket when available. NOTE: We also have standard 6C Long Blocks available when the fit just won't work with a larger extended long block version due to fuel pump or turbo mount issues.
