5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
I just got a 89 LX mustang I want to know if should take the PCV valve off and what kind of power could I gain. Also what kind of power adders would you recommend
you wont gain $hit from taking the PCV off, leave it alone you need it for the most part, delete the smog and put on an electric fan to free up some power, also bump timing and put in a k&n filter

RE: Removing the PCV valve
leave it along but you need to clean the screen, you can also get a high flowing one to clean up emissions
