I am currently installing a 1986 TPI engine in my 1965 Impala. I need some pictures and explanation of how the 2 heater hoses are connected to the motor. I have no hoses to try to install and need to buy something that will work. I have the heater core tubes coming from my firewall but need to know the best way to get this together. Thanks in advance. Pictures of the orginal 1986 setup would really help as we never seen the donor car the engine came from.

One Heater core hose comes off the firewall and goes to the nipple on the rear of the intake manifold.
The other hose comes off the firewall and will goto the port on the radiator, just under the filler neck.

Or you will have one port on your intake, and one on the water pump.
Hope this helps.

on my 87 iroc the two lines come out form the heater core, one goes to the back of the block, then one on the side runs to the front of the block then a 3rd hose that trails down the framerail to a metal line
