One common area of confusion is the meaning of theterms "piston deck" and "piston dome". The deck of a piston is the point atwhich the dome begins. Some pistons have a flat area at this point and somedo not. The dome is the very top of the piston, which in some cases extendsup into the combustion chamber, and in some cases is flat at the level of thedeck or even below. "Deck Height" refers to the distance between the centerof the wristpin hole to the deck of the piston. Piston deck height is neededto calculate cylinder length when designing an engine, or when replacing apiston in an existing engine.Order toll free 866-244-26739-20
