swap question

[Huck]

Since tj motors are hard to find in the salvage yards, I'm wondering if any of you can tell me wheter or not thre is another model and year of jeep that the block will interchange with my 06 Wrangler and its EFI system

99+ WJ and 00+ Tj motors will work.

Block casting number 53010449 is for 1999-2006 model I6 4.0L Jeep engines.

Can anyone confirm that they all have the same mounting points for all years and from all [vehicle] models?

good to know. i wasnt sure if the machining might be different for an Xj, or a wj form a TJ on stuff like motor mounts and accessory mounts
