I've heard much on the 4.0 head install... if you install the 4.0 head, that can be easily obtainable from a wreck... if you do that, you can use the 4.0 FI... you'll probably need the entire fuel system from it, computer, and a crank position sensor.. but i think it will give a better increase in power due to the head design.. i also think it would be cheaper[addsig]

	Crank position sensor A crank sensor is a component used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.
