Advice for all you car people!

Sometimes, when the question comes with little to no background information, responses can be inaccurate but may still point in the right direction.
What I've found is some responses to what is not even a question, but part of the plans for a particular build, some of the "know it alls" chime in with their opinions, often totally disregarding the op's actual plans for the project. That's just ignorance IMO.
