Hi Guys, I am trying to fix the problem with all the heat coming in to the cabin, have ordered a new heater control unit and will get the aircon fix as well.

The rear hood weatherstrip only goes down the sides about 12" or so. It doesn't go all the way down the sides. The purpose is to keep the hot engine air from migrating into the vent system, where the wipers are. New weatherstrip there will definitely help, but it may also make it a little hard to close the hood completely for a while.
Another area to check is for any open holes in the firewall that will allow hot engine air to come thru to the cabin area. Look for any grommets that are out of place where the wiring, and the speedo cable go thru the firewall.
Shark era Corvettes are notorious for being hot inside...it's part of their charm(yeah...RIGHT!).
You may want to look into installing some type of heat barrier under the carpeting, too, as that seems to help as much as anything.

Something else you might try is to see if your car has the "Front Tunnel Foam Heat Seal" in place. It's the foam collar that goes between the top of the transmission and the underside of the car. My 72 did not come with one, but I added one and it seems to make a difference. They way I see it is it directs the hot air coming from the engine compartment down under the car instead of it flowing through the tunnel. It's a $20.00 item. I think mine came from Eckler's.

 Strange as it may seem, I had a HOT AIR cabin problem as well. I changed the water pump and thermastat, and it made a BIG difference.   Used 165 and a new radiator cap.

Andy,

Thanks guys I will look under the carpet and check for the "Tunnell Foam", the MAIN source of the heat seems to only go directly on to my feet (very hot can not wear thongs, shoes only or they get burnt) and it feels like it is blowing in rather than radiating in
