How to learn how to build an engine from the ground up?

I'm 17. I also have the resources and all too. But I just want to build a fast engine. Maybe a ford racing or something like that. Is there a way I can find out what parts and the instructions i need and just order all of that off the internet or something? You will probably tell me to take a mechanics class but I'm planning on doing that next school year. I appreciate your answers in advance!
