As a teacher of mine likes to say, "the only dumb question is one that isn't asked." The only way to learn anything is to ask or read up about it, or of course experience. Some people when they post may be caught up in what they're asking and forget that they have to give specifics on their car.
I started out myself with a 4 cylinder mustang, and when i started learning about it i wanted options other than that wheezy 4 cylinder and i wanted to know how to swap a turbo or V8 in there. Now experience has taught me that it's cheaper just to buy a V8 car if you don't have a parts car or cheap available parts, but i didn't always know that. Everyone has to start somewhere is what i guess i'm saying.
Sometimes there are questions that are overposted on this board, but i just skip over them and go to other questions.
