    1999 XJ Cam Question

    I haven't torn it apart yet... but it went form a little annoying slap to a very loud horrible slap, lol. Really, it's bad. I don't want to break a piston skirt, and send metal shrapnel... rebuilds are generally pretty easy IMO. Couple weekends of time. I'm just interested in the cam options...

    1999 XJ Cam Question

    What valve springs did you use? Everyone seems to reference the MOPAR P5249464, but that is not a beehive style spring from what I can tell... so is for the earlier head, right?

    1999 XJ Cam Question

    I meant the *fears I have...* What I am getting at is I don't want to make the change if it's going to cause a lot of problems. I have read that the CPU's don't work well with a different cam.

    1999 XJ Cam Question

    Ok. So the gears I have come from a variety of other posts that say there is a significant drop in torque but a rise in HP forcing the use of higher RPM’s off road. Have you noticed any negative side effect of this sort? And which Comp cam did you use? Did you have to change anything else...

    1999 XJ Cam Question

    Hey guys, I need some help here. I developed a piston slap and so now I am rebuilding the motor. I have not pulled it apart yet, but I am planning on rebuilding the current motor basically stock (upgraded injectors were just done, and I assume I will bore .030 over...). I don’t t have the cash...
