POLL: Interior Heat
I hope at this point you have read some of the posts on the "Interior Heat" thread. I started this poll to try to determine if certain model years have the problem and others don't. We are looking for a very specific symptom, and you will know if you have it, where after 45 minutes or so of driving you feel like the soles of your shoes are melting. I am talking very uncomfortably hot.
So, I would like everyone to pipe in here, only once, as to whether you have this interior heat issue, and what model year C3 you are driving, and whether you have headers or not. If we find that only certain model years are the problem, then we may ask for further information from those that have the issue and those that don't.
Please read the "Interior Heat" thread to get a thorough background into what has been done...THANKS F22!...and a more thorough explanation of the issues we are trying to resolve.
By the way, my 74 coupe with stock manifolds and side pipes will cook you in 45 minutes.
Thanks a million!

72 vert sb, no real heat issues either side. It gets a bit warm on a hot day but mostly due to a black interior and so little air movement in the footwells. Headers and L88 hood.

69, sbc, 4spd, factory man. no ac, coup.
When I first got car it was a foot cooker. After reader about this problem on form, I checked
all seal point. Found bad seals around heater box,finder to fire wall seals,[cabin air vents].
and other fire wall grommets. After sealing foot heat reduced, by quite a bit.
Foot heat still high. Unable to test now, car down for power rack, Headers, And front end
upgrades. Thanks for all the work that is being done on this.

Is your car missing any of these shields? There maybe four, two on firewall, two on floor?

'72 L-48 coupe, 4-sp, no A/C and soles of feet and trans tunnel used to get uncomfortably hot.
Stuck on or laid down Hushmat to interior cabin firewall & floor, added Hooker sidepipes and no more hot feet or trans tunnel. Smoking ankles is now the avoidable option.

1976 stock manifold to true dual. Gets warm (Florida heat) in footwells but definitely not melting. I think with newer dynamat or similar it would be manageable. I do have a ball-valve on the heater hoses.

I think "heat issues" needs to be better defined. Obviously different people have different tolerances.
My vette feels like my saturn with the saturn's heater running at 50%... even though the vette's heater isn't even on, lol. Of course, opening a window makes it not overly problematic unless the temperature is over 100. However the wider I have the window open the more road/exhaust noise I get, so for long trips I'd prefer to be able to close the window a bit. Of course I can take the tops off and remove the rear window, which fixes the problem too and doesn't let in as much exhaust noise... but that's a hassle for daily driving.
Overall I would say I do have heat issues, but nothing that's going to kill me. My legs end up sweaty, but I don't feel like my shoes are melting, lol.
'71 BB, stock manifolds, AC which doesn't work.

70 coupe, uncomfortably hot after running for 45 minutes. Too warm around lower body even with roof off and window down.
No air con.
No kick panel vents. was air con car originally.
Fan will only blow warm air so makes interior worse.
Underfloor heat shields missing, firewall heat shields are in place.
Installed vacuum cut off to heater hose, helped a lot.
Under carpet is just standard underlay.
Heat shielding missing from transmission tunnel as is collar around bell housing.
