Our Street Series of engines are DFC’s flagship product for 6.7 Cummins upgrades. Built for work trucks, daily drivers and the diesel enthusiast in mind, these Cummins diesel 6.7 engines are a vast improvement from stock as they contain important upgrades to common problem areas. Street Series are Long Blocks with ARP series 2000 head studs or OptiTorque head studs depending on availability.
What's up with the Retro Block?
DFC offers remanufactured 2019-2024 6.7L Cummins engines, focusing on upgrading weaknesses of the stock design, such as replacing roller lifters with more durable flat-tappet systems, installing stronger components (cam, valve springs, heads), and using better sealing (silicone vs. paper gaskets) for reliability, using 2018-era components on the blocks for longevity. These "retro" builds aim to restore or exceed OEM durability, addressing common issues like camshaft/lifter failures and weak blocks in the 2019+ models, which are known for having lighter blocks and problematic valvetrains compared to earlier years.
