The 2.3 block found in the scorpio and galaxy has anti vibration shafts in the sump. so if you want to use this block you will have to have a one off downpipe fabricated to clear the sump or use the 2.0 sump taking out the anti vibration shafts out of the 2.3 buy then there is a big gap in the side of the cast from where the drive chain runs thru to the shafts so will have to get an ally block fabricated to bung the hole up. Also the head from the 2.0 will work with the 2.3 block but will have very high compression ratio so will need to run high octane fuel to stop any detanation. hope this is of use to you.
