From what I can recall( not much these days) is the stick on the intake side of the block at the front of the block?,
Did you get supplied with the dip stick? if so check it with the original and see if it is the same.
I had a problem with the hilux where I swap the blocks and the stick hit the windage tray in the hilux sump. drilled throw windage tray and it was fine.
Also check the pick-up is in the right place in the sum!
