how much money do you have to spend?
What kind of tools do you have? Do you have a library of how to build engine books? do you have a GOOD engine stand? Do you have a place outside, not in a basement to build your motor? Do you have anyone to help and learn build? Double check every move you make. Like when you build something and they say measure twice, you need to double check what you are doing. I would like to say I taught myself but I didn't , my father taught me the basics and I have grown from there. Good luck and I know we will be hearing a LOT from YOU! OH YEA, ask questions even if you think you know what you are supposed to do, it will save you $$$$$ and headache's.
