you need the 2.3 from a scoprio as the galazy has the block the other way and the mounts aren't the same
the holes are there but they need fiddling with
besides, the scoprio is much cheaper and if you get a manual you've got the box to go with it and, more importantly, the bigger clutch/flywheel package as well
jim's fitted the 8V head to his and with a bit of thought is knocking out 170 brake with fooked bores
besides that, the other advantage is that you can just say it's a 2..0 and no one will be any the wiser unles they look fo the tell tale casting marks
