Why should you let Pro machine bore your engine block? We bore the engine block with precision off of the main webs at 90 degrees on a v8. On some v6 they are 60 degree . We bore all inline four cylinders and 6 cylinders off of the pan rails. We can also align hone your engine block. We can also hone your blocks with precision and care to the best of our ability. The machines we use are Rottler and Sunnen equipment. Also to finish a block pro machine requires all the pistons so that we can fit each bore to the size of the piston.
