Abstract: A machining process is shown and described. The process entails removing the water pump from the front of the block and replacing it with a block-off unit. The cylinder head is removed and replaced by left and right torque plates that are attached to each side of the block. The torque plates provide fluid connection of the smaller coolant passages on each side of the block with one another. The boring process is performed on the engine block when such engine block has been heated to a temperature at or near its operating temperature via the fluid passages. A boring machine may enter the cylinder bores thorough larger openings in each torque plate. The main bearing support (caps) can also be align bored during this process.
