Abstract
A multiple cylinder internal combustion cylinder block having a cast exhaust manifold means integrally cast with the block is disclosed. The manifold means includes manifold port portions that communicate with the cylinder bores, and an expansion slot is provided in the manifold port portions adjacent the cylindrical bores to relieve stress that tends to distort the cylindrical bores of the block.
