Custom Long Block Engines

This category houses custom long block engine assemblies built by Unique Diesel of various combinations. Some of these long block engine combinations are build to order allowing customer selection of options. The base long block starts out as the same new production unit sold in our stock long block engines category. Engines are assembled to specification based on tested and true durability and performance options. Only options that truly add performance and durability to the engine assembly are offered. Modifications that make changes to the engine only to cause a compromise down the road are not found here.
