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. This is a ready-to-assemble sleeved block that has all the necessary machine work done and all the clearances checked.
Each prepped block will start with the following:
- Hot tank cleaning
- Sand Blast Block
- R/R Small Block Parts
- Darton Sleeves Installed
- Bore/Honed with Torque Plate
- Step Decked
- Line Bored
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. If there is not a block listed, then we are out of cores.
Select the bore size you wish.
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.
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.
The surface 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:
You get a choice of how we will address the line bore (where the crank sits) of the block. If you plan to use the stock main bolts, then none would be your choice. If you want upgraded hardware, then select the ARP Main Studs. This will include the main studs and line boring of the block. If you plan to make some serious power, then choose the Billet Main Caps w/ 1/2" Studs. This will include the caps, hardware, 1/2" main stud machining, and line boring.
Our line boring starts with a simple cap grinding. From there it goes into our line boring machine. With our custom tooling, we can bore the main journals within the factory specifications with ease.
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.
R/R Block Small Parts:
This process includes removing and replacing all the freeze plugs, oil passage plugs, and transmission dowel pins. Parts are included.
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.
