firewall, then 2 short rubber hoses. (one has a restrictor in it) into 2 steel hard lines bolted to the intake. one hard line has a fitting that screws into the intake with the computer sensor, the other goes into another rubber hose and into the water pump.
heat was bypassed when new motor went in...its a carbed 331... wanted to hook heat back up, thats why i was wondering what hoses go where and if i could see pics how its run...
In this pic you can see the hard steel lines that stangster was talking about.
In this pic I circled the heater core lines that come out of the firewall, this is where the two short rubber lines go in between the hard line and the heater core. You can also see where the hard line connects to the waterpump.
I can't find any good pictures of it fully assembled so I hope this helps.
