I am looking for information on How to resurface a 6nc catapillar engine as well as cummins and detroit diesels. My father just had to have his block resurfaced in his Peterbuilt and the guy that did it was able to do it while the engine was still in frame. I can find portable cylinder boring machines, line boring machines for the crank and valve grinders but nothing for cylinder heads and to plane the engine block. His was cut for a .032 shim and the guy did it all by hand. Anyone know where I can find what he would have used to do it or know the name of what was used? Theres a high demand in the area I live for work likes this and its something I want to start doing on the side for a little extra work.
