OK guys, I am having troble with a desition i want to make. I am not sure if getting FI will be cost effenct and worth it with a 4.0 head. (will my 258 with the above, still only be worth about 5?) If That is not good, should I purchase a 4.0 YJ? ( I personaly like the looks of YJ's) OR should i hold out and wait to see if this Rubicon thing ever gets put in production? This biggest problem is I love the Torque the 258 makes. What would you do and why? Thanks...
