Block prep package: This upgrade includes notching the block on our Centroid cnc machine to allow additional clearance for the crank if necessary. We also de-burr the block, hone the lifter bores to spec, chamfer the top of the cylinders, and lifter bores, and install the special Dart cam bearings and freeze plugs. The block is then thoroughly cleaned in our block washing machine. We find this upgrade essential for those lacking the proper equipment or knowledge to perform this correctly.
Preparing the block in our Centroid cnc machine for precise notching, if necessary.
The blocks are washed in a dedicated block cleaning machine.
Pictured above is the final rinsing and drying to remove the cleaning solvents.
