Can you interchange a 2000 grand cherokee 4.7 with a newer year grand cherokee4.7?

I purchased a 2000 Jeep grand cherokee with a 4.7 that is unrepairable. What engine can be swap with as far as newer 4.7's? Ive heard that you can only swap 1999 - 2000 4.7 non high output engines with same vin (N)..Also i heard that it can be swapped with a 2001 - 2004 engine as long as its a 4.7 standard with same eighth vin (N). So im stuck between a rock and a hard place with this vehicle. Finding a decent engine with decent mileage that is compatible is beginning to become very frustrating. If you have any information i would be very thankful! Thanks in advance cchopp0178 !

Yours has a 16 tone wheel on the crank and passenger side cam. I believe that this was thru mid year 2002. After that it was a 32 tone wheel on the crank and cam. They can be swapped out but requires removing the crank from the block to get the wheel off of the crank.

I am looking at a 2001 High Output 4.7 engine to swap. Between standard and high output 4.7 engines the only difference is the tone wheel? Is the crank pulley the same? sensors the same? would i have to tranfer the sensors from 2000 to the 2001? Thanks in advance!

To do the HO engine, you'll need the wiring harness and ECM (computer) as well, as the HO has an extra knock sensor and a 4 plug harness into the ECM as opposed to the 3 plug on the 16 tooth'd non-HO early 4.7.

You would be better off getting an a non ho engine and putting new cams and maybe getting head work and a new intake the engine. You would have more hp and not have to worry about the pcm and harness being different. If you can do the work your self I would get the newest engine you can find up until 2007 and swap cam and crank tone wheels. While you have the engine apart put new cams and maybe pistons in and get some head work done and put a new intake on and your engine would be faster then a ho. Plus you can find a newer engine with low miles for around 1000 comparded to 2000 so you can use the extra money on upgrades. AirRam - Cold Air Induction System can hook up with what you would need.

Are the HO engines 16 or 32 tone on the cranks? So they use the 4 plug ECM and not the 3?
