I just got a 72 mach 1 with H code engine and ram air. This is my first mustang and needless to say I have a lot to learn about this car. I was wondering what the horse power is with the ram air set up? I also noticed that there are a number of vacuum hoses that are not hooked up or missing altogether. The engine seems to run fine, but with the weather here in Ohio, I was only able to take it for a short drive when I got it. Is it a common practice to not hook up certain vac lines?
