Here at Mazworx, we can prep your block to your specifications. Utilizing our CNC capabilities and state-of-the-art equipment, you can ensure that the machining process is done properly. If you want a sleeved block that is ready-to-assemble, see the specifications section for info. For more understanding of our process, see the additional information section.

Each prepped block will start with the following:

- Hot tank cleaning
- Sand Blasted Block
- Darton Sleeves Installed
- Bore & Hone w/ Torque Plate
- Step Decked
- Line Bore

Core:
If you plan on sending in your block, we will wait for your block to show up before work is started. If you don't have a block and want to purchase a core, then please select the type of block you want.

Bore:
Select the bore size you wish. For turbo applications, we suggest limiting the bore to 89mm.

Our boring process is done on a 3-axis CNC machine ensuring bores are on center. From there it goes to the honing machine. We have the latest Sunnen SV-10 cylinder hone with diamond tooling. This is for the ultimate in cylinder finishing.

Sleeves:
When planning on making 400hp, putting sleeves in is a must. Darton MID Sleeves are made of ductile iron and are able to hold over 1000hp. This process includes the removal of the old sleeves, machining the block for the new sleeves, installation, and step decking.

This process is done on our 3-axis CNC machine.

Surfacing:

The surface of the block will be step decked.  This is done in our 3-axis CNC machine. We machine the surface so that the sleeve is taller than the deck of the block (also known as a step deck). This concentrates the clamping force around the sleeve to help the head gasket seal under high boost.

Main Studs/Caps and Line Bore:
Since this block has a integrated girdle, we line hone the block to factory specifications.

Sand Blast Block:
Since these blocks can be over 20 years old, they may start corroding. Sand blasting the block will get the corrosion/debris off, bring a uniform satin aluminum color to the block and give it an overall better look.

Hone with Torque Plate:
We make all of our torque plates for just about every block we work on. Using a torque plate simulates a cylinder head being bolted on during the honing process. When the motor is actually put back together, the cylinder is as true as it was while in the honing machine. Using the torque plate is a must with sleeves install. It is an option on stock sleeve blocks.
