Everyday I sit in my auto-cad bored out of my mind trying to find something to do. Every project given to me by the instructor takes me a quater of the time than the rest of the class. I would like to draft my engine block and maybe even the heads. It will be challenge but that will make it all the more fun. I was hoping that you guys could help out with providing dimensions such as cylinder width and height, block length, and all those other goodies. Hopefully there is a drawing with specs floating around there somewhere, if there is that will be most helpful. Well thanks for all your help!
