I'm totally new here, and hardly even a rookie about cars. My dad has been working on mustangs since he was a teenager, though. So right now we're working together to replace my '94 mustang's engine with an '01 -- it had the fewest miles on it. We've still got the original engine for parts (i.e. the '01 engine has a cracked valve cover so we'll just use the one off the '94). Anything I should know up front? I've only got a couple weeks to finish this project.
