Auto Shop Research Help

I am in highschool and my Auto Shop teacher is making us do a project on Engines. My group has chosen to do the Engine block as our project but we are not able to find good enough information to use :confused: . If anyone has any suggestions on where I can find the information or if you know anything about the engine block. I'd really appreciate the help. I also need in depth information on the intake and exhaust valves if anyone could help me find some information on that I'd really appreciate it. REALLY!

You can get a lot right here. What specific information do you need. Metal selection, Casting techniques, technical evolution. Just let us know. Someone here will have the answer for you or get you links so you can find it. Good Luck.
