|2005JGC||The wk and wj 4.7l engines are different. Different tone rings. The PCM wont know how to interpret the engine speed. The cam gear can be swapped but the crank tone wheel is built into the crankshaft. Whatever engine you get, pop the valve cover off and verify the cam tone wheel is the same as what ya got.|

Blue book right now is between $4-6k depending on condition.

If there is significant rust underneath, pass on it.
I am the original owner of a O5 4.7L that now has 90,000 miles. If the engine is blown there is an excellent chance that other significant expenses will follow once a reman engine is installed. Have to figure the owner did little if any maintenance. Set aside an additional $3,000 minimum new parts budget for this 13 year old vehicle plus the cost of the new (Promar) reman engine, shipping, and installation for $4,300 ($2,800 + $300 + $1,200).
What is blue book value now, about $6,000?
(wheel bearings, struts, shocks, tie rod ends, brakes, maybe catalytic converters, radiator, water pump, hoses, fuel pump, tires, battery, fluids (tranny, radiator, differentials, transfer case, power steering, and brakes), etc)

WK 4.7 replacement engine
I'm looking at buying this 05 WK with 88k miles on it for a whopping $400. It has the 4.7 v8 and it's blown for whatever reason.
Good used engines seem pretty pricey, in the $2k range around me (NJ). Can I swap in a 4.7 from a WJ? or at least use the 4.7 shortblock and put the newer 4.7 accessories, heads, intake, etc. on?
Anything else to look out for? I'm an XJ guy so I know my way around Jeeps just haven't ever bought a grand cherokee.
