Dart Big-M Block Machined Upgrade - Scratching The Surface
|
After the measuring and recording were complete, our Big-M was ready to begin the machining on the CNC. Initial measurements showed that our lifter bores measured 0.842 inch, but we needed 0.904 inch for our lifter bushings. A lifter bore cutting tool was added, and the CNC began to hog out each lifter bore in order to gain the clearance for our CHE lifter bushings. View Related Article
