heater hoses for sbc swap

[tys]

I've swapped in a sbc tbi motor (88) into my 79 CJ7. I'm confused as to what goes where. There's only one fitting (excluding the radiator hoses) at the rear of the block, coming out of the intake manifold. I presume I need to run a hose from that to my heater core. Where should the other hose go (output of heater core)? There isn't another fitting on the engine and if I remember right from the donor vehicle, this other hose ran to the radiator. My new radiator only has to large fittings for the radiator hoses. Can I get a different water pump or pick up a fitting to put inplace of the plug on my existing water pump? Will it flow properly and in the right direction? Any problems with doing something like this?

That fitting by the distributor is the return line that comes from the heater. You need to either feed the heater from a bung on the radiator or plumb it off a fitting from the water pump.
