???????Block casting number 344 66????????

I have been looking for hours and cant find any info on my block

I have a 91 wrangler 5spd that I think the motor has been changed out when locating the number on the drivers side of the block near the motor mount the numbers I find are 344 66 on the passenger side the build date is 701m22 and the letters above the starter are H1 and to the right in bigger print is BT

If anyone can help me with this please do so I need to replace the engine and what i thought was a 4.0 I now am not sure the motor that i do have is EFI and looks to be a 4.0 however the block is not matching up to any casting numbers i have found
