So I just drove my 1960 thunderbird home from Tulsa ok to Nebraska. I was blown away at how good it ran. I'm newly in love with a Ford, being a Mopar guy in the past. However, the heater didn't work so good. Am I to understand that the car does not have a heater core? How does this system work? Any info, greatly appreciated. Also, how do i attach pics? Thank you

There is a heater core in the plenum chamber, you can see the heater hoses going to the firewall in the engine compartment. There is a thermostatic valve which controls the flow of coolant going to the heater core.
You can only attach pics when you are a paying member. You can use a foto charing site like photobucket.com and post the link on here.

As Frank mentioned make sure the two heater hoses are connected to the core at the passenger side firewall. Many times when the core leaks the hoses are looped to bypass it.

Check the thermostat too, T-Birds are prone to running hot, so I've heard of people removing the thermostat thus not creating enough heat to run the heater with hot air coming out. also it's pretty simple to remove the controls and check the cables, they might be out of adjustment. Simple things first. When you have the car running, move the controls and you should hear it switching between heat and defrost, the blower runs like s**t on low so run it on high, but when it works its a cooker!

Here's how it works for a car with A/C.

The Non A/C car would not have the evaporator on the outer firewall behind the engine and would not have the flap or "valve" in the picture that is controlled by the left knob. The air from the fan would go directly to the heater core.

Here's the heater plenum that is under the dash and contains the heater core. It has small openings molded along the seam to direct air to the passenger and driver area. The two round holes in the bottom portion of the picture is where the defrost ducts connect (the plenum is separated into two parts in this pic)

And here is the core from the engine compartment with the fan box removed. Air is drawn from the circular hole via the squirrel cage fan, directed across the heater core in the square hole and on into the heater plenum under the dash.You can also see where the water connections are located.

And a car with the A/C plenum installed on the firewall next to the fan box.
