Dependable Heavy-Duty Workhorse
Choate has taken the 6.7L Powerstroke to the next level of durability and performance with their 6.7L Workhorse Long Block. This heavy-duty engine is designed for heavy-duty towing and other tough tasks that demand power and reliability. Including several significant improvements over the Choate Daily Driver, including O-Ringed Heads, Billet Flex Plate, Coated, Fly Cut and Delipped Pistons, Stage 2 Cam, Chromoly Pushrods, and Welded Cam Gea. Choate Engineering built their 6.7L Workhorse Long Block to live up to its namesake and be a tough dependable workhorse.
Improved and Enhanced 6.7L
The 6.7L Workhorse Long Block is built to higher quality standards than the OE and solves its biggest issues. One issue tackled is the Main and Rod bearing clearance problems in the OE 6.7L. Choate achieves this through precision machining for correct clearances and using upgraded bearings designed for higher stress levels. Another concern is potential separation of OE 6.7L exhaust valves, which can cause engine failure. To prevent this, Choate installs heavy-duty valves resistant to high temperatures. Additionally, they address cam tunnel misalignment by using proprietary bearings for perfect alignment. For a hassle-free fully running crate engine that surpasses the OE 6.7L, Choate Engineering's 6.7L Workhorse Long Block is the top choice for an engine that tackles the heaviest tasks with ease.
