Abstract
A cylinder block for an internal combustion engine is provided which includes a cooling jacket having a peripheral wall forming the exterior of the block and a plurality of cylinder tubes disposed within and encompassed by said wall. A plurality of depending openings or bores are formed in the top surface of the block to accommodate a corresponding number of bolts for assembling a cylinder head on the block top surface. Each opening is internally threaded; however, the threads within the openings commence at different levels relative to the block top surface. The level at which the threads commence will depend upon the location of the opening with respect to the cooling jacket peripheral wall. Thus, the greater the distance the opening is from the wall, the threads thereof will commence within the opening at a greater depth from the top surface of the block.
