DHD's Duramax engine program is known nationally for its durability, attention to detail and quality components. You wont find the value that this build offers anywhere else.

DHD's Budget Hooker builds are designed for customers looking to increase reliability and performance at a moderate level. Our Budget Hooker Long Block is by far the most complete production build configuration. Its perfect the customer looking for a professionally sealed and prepped engine ready for fuel and air components. Much like the standard budget hooker short blocks, the long block is an unbeatable value!

Due to nearly infinite variables its very difficult for us to assign a horsepower rating to this build. We can however assure you that many of our customers are successfully running this build with 600-750HP. These build components pair well with upgraded turbochargers and injectors.
