Small Block Water Pump Bypass Hose 360 LA?

The one you have in the picture above is the large one 63735. If that is to big you need the 63642. These are old Goodyear numbers which are now Continental, which is available on Rockauto and I'm sure at your local parts stores. With that in mind you must have a cast iron water pump and the smaller nipple in the intake. Let us know what exactly you are working on-what type of intake?
