This is a 1998 XJ 4.0 with some improvement’s. Headers, hi flow cat, Gibson muffler. On the other side is a 62mm TB, cold air system (although there is not too much gold air under the hood to be had) 24 lb 4 hole injectors and a high output coil and plug wires that allows me to gap the plugs to 56/100 . I am going to put on 1.7 roller rockers this Friday.
Now I am stuck and a little confused as to what I what to do next. I want to put on a really good head and then a cam but I am not sure if what I want is the right thing.
So maybe I should explain what I am trying to accomplish. This XJ has 196,000 on the odometer and is a very healthy motor. I will be rebuilding it totally around the 250,000 mark putting in the biggest crank and pistons I can (I would love to put in a 4.060 crank) but for right now I am building this little by little top to bottom putting in parts that will work with each other that will help me reach my final goal.
This is my goal ; I want the torque to come on hard around 800 and to continue to poll hard up to 3000, running flat to 4500 then dropping off. This xj is going to be a do all and be everything jeep. It needs to crawl when I need it to, tow a trailer and cruse all day at 70 miles an hour (that is about 2500 RPMs for me). On regular gas.
I would like a head next but, I am not sure what head. I have read so much about heads my head is swimming, very confusing. I am not understanding what kind of head I should put on to maximize what I have now and to add to the end goal.
any advice?
thanks guys
