I thought I would remember where they went, must be getting old! LOL
I have a 302 from the 70's, there are two outlets on the water pump for heater hoses, and one on the thermostst housing. There is a fitting on the manifold and two heater hoses on the firewall (in a 56 f100) an upper hose and a lower. Anyone have any diagram, or can anyone take a look at their smallblock and bail me out??

not real sure,but should be one hose coming from the heater core to the water pump,
another hose from the heater core to the intake, the other hose on the water pump should be a bypass hose that goes to thermostat housing.
If your engine is the same as mine (a 85 302 EFI) there are 2 spots on the water pump for heater core hoses. The upper one goes from the waterpump to the thermostat housing (bypass hose) and the lower one goes to the heater core (right side I believe, if looking from the front of the truck). The other heater core hose goes to the engine. Hope this helps.
P.S. I may be wrong but I don't think it matters what heater core hose goes where. Just make sure you have the bypass hose right.
