I don't think any diff. it was just diff setup made due the location change of some stuff into engine bay.

The change allowed to fit the steering pump deeper into engine bay, then on smogger engines fit the air pump over this.

also not more belt iddler pulleys at Water pump being the steering pump works like the belt iddler

but talking about OUTLET SIDE ? I don't think any advantage or disadvantage
