I used gas shut off valves from Home Depot

Lots to digest in this thread.
my new to me ‘77 gets really hot around the footwells.
Was out in it with my fiancé about 2 weeks ago, and the first 30 minutes were fine, but once we got into traffic, it got pretty hot around our feet.
when it’s time to start the ‘restoration’, I’ll be coming back to start implementing some of the various changes, starting with the check valves for the heater core.

This is what I have had done to my 76 to reduce cabin heat. 1. insulate floor pan and firewall-this would be the first thing I would recommend 2. cutoff valve on water line to heater core 3. ceramic coated headers 4. wrapped exhaust pipes 5. tinted windows and windshield-shortly after the installation, waiting at a traffic light with the sun hitting me directly on the drivers side, I was surprised how much the heat was reduced when I raised the window 6. installation of a blower motor with a larger squirrel cage-I had to make a 3/4 inch spacer to be placed on the firewall due to the extra length squirrel cage. The amount of air being pushed by the blower makes a difference. My A/C keeps me cool and I live in Central Texas where it is hot, especially in July and August, and we have been breaking records this year. I just returned from a 3600 mile trip out West in the Vette, and the temperature was reported to be 114 degrees when I went past Las Vegas on

I-15. Of the newer Vettes, I like the appearance of the C7 best. However, I think the shape and appearance of the C3 is the best of all the models which I guess explains why I still have my C3. During the stops for gas which are many, during my trips out West(this was the 4th in the Vette), it is the exception when there are no positive compliments on the Vette.

That's my idea of fun.

Are these gas valves working ok? I'd like to keep it simple if they work welll. Do you have a picture or part number?

FWIW if applicable to your car check to see if the “Firewall Splash Shields” are in place, not a heat shield necessarily but they do cut down on the toasty floor syndrome…

These, along with the ignition shielding and spark plug heat shielding are typically long gone on these cars.

Best of luck!
