any body have this on their 4.0, what did it take to install,can you install it, how was the performance increase ( i know to really get any kind of increase u need other mods) was it difficult did u need a new valve cover. TIA
and yes i am a newbie (':flipoff2:')

Clifford makes a spacer for the valve cover. From what I recall when I researched this the amount of money and machineing required made me deside to skip this. Check you the Yahoo Groups there is a group dedicated to jeep strokers allot of these guys have played with this type of thing
