Reman blocks what years are compatible
 

I'm looking to buy a reman short block for my 2001 xj not sure what all years are compatible and if anyone has suggestions on the best place to get one

Thanks for the help!

XJ Cherokee and ZJ Grand Cherokee 4.0L engine blocks interchange.

2000+ TJ Wrangler and WJ Grand Cherokee 4.0L engine blocks interchange.

XJ/ZJ blocks, and the 2000+ TJ/WJ blocks do not interchange without significant modifications. (1991 to 1995 YJ and 1997-1999 4.0L TJ Wrangler blocks will interchange in XJ/ZJ and visa-versa).

TJ/WJ 4.0L Engine blocks underwent clean sheet design changes effective in the 1999 WJ Grand and 2000 TJ Wrangler. These blocks are not interchangeable with XJ/ZJ engine blocks. The reason is motor mount bolt holes and belt driven accessory mounting bolt holes are in different locations, or not present at all, TJ/WJ vs. XJ/ZJ.


XJ: "Regular" (not Grand) Cherokees 84-01
ZJ: Grand Cherokee 93-98 (Gen1)
WJ: Grand Cherokee 99-04 (Gen2)
YJ: Wrangler 87-95 (Gen1)
TJ: Wrangler 97-06 (Gen2)

Every time you post this, it reminds me of the logic games on the LSAT. It seems like it should be followed by a question such as: "If Cruiser has 2 2001 XJ Cherokees, 5 WJ Grand Cherokees, 3 ZJ Grand Cherokees, 7 TJ Wranglers, 2 YJ Wranglers and one LS motor with all adapters for an XJ swap, what is the maximum number of engine swaps he can complete?"

lol. no caps now as cruiser is holding a granddaughter on his lap in front of his pc.

Dumb question but just so I'm completely clear, I can use any year xj/zj block and it will be compatible with the DIS my 2001 uses?

Yes.

uh oh. She'll be giving advice on the XJs before we know it! Cruiser56 (assuming son/daughter is Cruiser55)

This is her big sister. She's 4 now.

Haha no way. That's awesome!

I see a Fram oil filter on your work bench? I thought those were like your kryptonite!

Here's why. It was a gift from rononifako last Christmas.

HAHAHAHA!!! Yes! Thats fantastic!

This was a normal thread. Then somehow it suddenly filled with win.
