ID a 4.0 engine is it from a grand or sport??

I have some pics of a engine a guy is selling that belonged to a relative he knows it was bought to put in a XJ sport but thats it. I took several pics so my question is can anyone tell me if its from a grand or xj as I know in the 2000 year range they are different.

You want to get the casting number off the block.  Then post it here.  Certain late blocks will not bolt into the earlier MJ/XJ - I have one of those blocks in the garage!

4.0 Engine date codes

 

The date code is on the passenger side of the engine, on the block, just forward and up from the distributor on a machined flat surface.

 

The digits of the code identify:

 1st Digit-The year (8 = 1998). 

 2nd & 3rd Digits-The month (01 - 12). 

 4th & 5th Digits-The engine type/fuel system/compression ratio (MX = A 4.0 Liter (242 CID) 8.7:1 compression ratio engine with a multi-point fuel injection system). 

 6th & 7th Digits-The day of engine build (01 - 31). 

1. FOR EXAMPLE: Code * 801MX12 * identifies a 4.0 Liter (242 CID) engine with a multi-point fuel injection system, 8.7:1 compression ratio and built on January 12, 1998.

Well I was down talking to the guy again and his sister pulled in we were talking her X Boyfreind bought the engine for her jeep she was driving (xj), I said can you give me more info she said they ended up with it as a spare because they  really bought it for a grand and it would not fit, so they stashed it as a spare for her XJ. So with that I bought it they had left everything on it so it looked like a 2000-2001 with the correct intake coil pack  double cats still on it. After getting it home I noticed no bolts in the coil rail then started looking more at it.

Now I check the date code its a damn 94 when he told me a 2000. I always wondered if I could put a older engine in a 2000 and thought it could be done so I will find out. They obviously had it in a 2000-01 with all the new stuff on it even has the electronic dizzy in it.
