Anybody know the stock compression ration for the '02 4.0L? I'm looking at some cams the recommend 8.75 - 10.5:1. Anybody raised their compression? Thanks

Well, I finally searched Google for a bit and got the answer. The stock 4.0L is 8.8:1. ...So now I know that I'll have to shim the head or get a thicker gasket to offset the 9.0:1 compression pistons that come with the stroker kit I'm looking at... Otherwise, the forced induction is going to be an issue.
