ATK Marine DM02 350ci Rebuilt Long Block

ATK Marine DM02 High Performance Rebuilt Long Block engines provide a robust high-performance marine powertrain solution designed for reliable operation in demanding aquatic environments. This 5.7L 350ci Small Block Chevy build features cast-iron cylinder heads and a seasoned block, engineered to maintain mechanical integrity under sustained marine loads. Built with a hydraulic flat tappet camshaft and a precision internal balance, this remanufactured unit is a direct performance fit for inboard marine applications requiring a dependable 350ci foundation.

As a Stage 1 remanufactured marine foundation, the ATK DM02 arrives in an un-dressed state to allow for full build customization with marine-grade accessories. While this long block includes the cylinder heads, builders must provide their own intake manifold, oil pan, and ignition system. Backed by a professional 1-Year limited warranty, this unit features a traditional 2-piece rear main seal and is built on a seasoned cast-iron block for long-term durability in recreational or commercial boating applications.
