The motor now has over 500 miles on it and the oil and filter has been changed. The oil was very clean and I did have to tighten a few thing here and there that loosened up during the install (a hose clamp for and the few bolts for the headers. The motor is still breaking in and still puts a smile on my face when I drive it. More to come! The motor is now broken in @ 8000K miles and it is running smoother. The oil is very clean and it is also quieter as well. The torque is very impressive and I did get a chance to let a friend drive my TJ and he said there much noticable difference between the two motors (I guess I'll be helping him with the install).
5000K report: The motor runs great, still running regular unleaded fuel. Nothing but routine oil changes.
