Wrong. I just ran my cross member about 1/2" forward, because I have a tube chassis up front.
Issues withe transmission. You "can" simply just bolt up the transmission to the KA block, but.... the transmission will sit about 10 degrees to the the left , so the shifter will sit towards the driver side, instead of sitting straight up and down.
Issues with removing the power steering pump. The same belt runs the water pump, so you can't just remove it.
You'll need both alternator brackets from a KA24"E" (sohc) engine. This will locate the alternator about an inch back so it runs inline with the water pump. Then you will also need a thermostat housing from the the sohc engine, because you'll run into issues of the belt rubbing if you use the dohc housing.
