Xj block

I have an 01 Cherokee 4.0. And I threw a rod through the block. Do I have to use an 01 and up block, or can I use any 4.0 block?

Any XJ Cherokee, ZJ Grand Cherokee 4.0L engine block will interchange.

Remove and re-use ( or replace with new ) as needed or required from the original engine: Intake/Exhaust manifolds, flex plate/flywheel, cylinder head, water pump, distributor-less ignition or distributor assembly, OBD engine sensors, fan belt driven accessories, and/or mounting brackets.


A recent Gallup public opinion poll shows the NRA, at 58% approval, has a higher approval rating than either Hillary Clinton or Barack Obama.

I would probably use a 96-99 block. They will have the dowel pins for the head. Not necessary, but nice to have. I think the difference in the 00-01 block is 'improved' main bearings.

Plus if you can get the head with it, you could dodge the 0331 with that year range.

I think piston slap issues started in 96. You might want to consider that too.
