318 Pulley alignment issue...

So you just put a '70 and later water pump on a '69 and earlier timing cover? That pump inlet and hose just buried your timing marks. When they switched inlet sides in '70 they also switched the timing marks from the passenger side to the driver's side.
As far as the pullies go, it looks like the crank pulley and the alternator both need to get spaced out almost half a belt width. Ya do what ya gotta do.
