360 radiator inlet and outlet?

It really is up to which water pump you use, either will fit the 360.
70 up wp is passenger side bottom, driver side top.
Prior to 70 driver side top and bottom

If you are using a stock 360 balancer then for ease of timing use the 70 up wp. Although I did use a 70 down wp on a 360 and it wasn't that bad to see the timing marks, past the lower hose.
