We not only supply Darton sleeves but can fully machine your block in our state-of-the art machine shop.

The machining process involves -

The block is loaded into our Haas CNC for initial machining

Following the initial CNC machining, the block is placed in the large oven and heated to 220 degrees Fahrenheit for 20 minutes.  After the heat soak the sleeves are fitted and pressure straps installed to help insure the sleeves will not sink after final machining.  the engine block is then placed back in the oven, reheated and then left to cool.
