Small Block Water Pump - Bolt Locations ?

-- Wrong water pump - hose connection is on the other side.

The water pump itself isn't the point, the bolts that go into water jacket are.
All four of the long ones, two above the coolant ports in the timing cover and block and two below.
Here's a different pic if it makes you more comfortable.
This is right of the Ramcharger central site and a 318.
