My car was originally a TPI, I'm on my 3rd engine now which is a 355 that I built and I swapped the car to carb'd. I haven't had heat for 5 years due to a defective heater core. Well I finally replaced it and I ran one hose to the water pump and the other to the top of the radiator.. The heat sucks, it gets luke warm at best when I'm beating the crap out of the car (engine sits around 180-190*). I have a port on the water inlet (thermostat housing) and also a couple on the intake (edelbrock RPM air gap), should I go to one of those instead? I'm pretty much daily driving it so the lack of heat is killing me..

thanks guys, Tim

Yeah your just getting constant water flow, you need either a hose going to the intake, passenger side and the waterpump, or the intake and the radiator.

So what you're saying is I need to put a "T" fitting into the hose going from my radiator and connect it to my intake? or am I reading that wrong? lol

thanks!

You want hot engine water going into the heater core, then returning the water back for reheating.

Hot water comes from the intake. Return can go either to water pump or the rad. My choice would be rad since the water pump hole is easier to plug.

Tim; Plug the upper port on the radiator with a rubber cap. That radiator coolant port was used with Fuel Injected cars, not carb. ( MAYBE the 87 carb cars !?! ) The rubber caps will only last 1-2 seasons so buy a package from the "help" section of the parts store with a couple in it and leave the spare in the center console till you need another one.

Here's a pic of my 84 when the 355 with RPM intake was still installed. Once you install your heater hose lines like this, it's just a matter of installing a thermostat with the proper temp rating. ( if you've got a 160 stat than it will NEVER warm-up ! )
