Yep, had a buddy with a 68 with sidepipes. Burned the back of my ankle something fierce! gettting out of it. Damn, that hurt! Still have a scar after 25 years.
my wife and I both bear that scar. I remember when I got mine. I had been working on the car, got it running clean without breaking up at 6500 rpm. just got back home from taking a neighbor for a ride. I told him to be careful getting out to not burn his leg and immediately burned my leg after that.

you can always pull the carpet and add additional heat shielding. It does help a great deal, just be sure to get the good stuff.

I would add another heat shield, under the cab, above the Cat. Converters. It should be cheaper, and faster than adding a heat shield to the entire cabin floor.

I think you’re right. After doing a little research, I think this might be the easiest solution for me.

After a while, and some research, you can always add a good sound deadening/heat shield, to the inside of the cabin floor. Insulation on the hard top ceiling would also cool the inside a lot.

This would be my suggestion, too. If you *really* want to do it right, and you're not in a state like CA which forbids such actions, pull out the stock cats and install hi-flow cats with extra heat shields welded on the top of them. I did this with my Grand Cherokee, and it's worked great. Just make sure you have a heat shield welded on that leaves about 1/2" of airflow between the top of the cat and the shield.

Another option (popular with Vipers) is to use Aerogel shielding wrap. Vipers get stupid hot and the Aerogel really does a great job. Problem with using that on a Jeep is that Aerogel doesn't handle being soaked in water too well. So, that's probably not an option unless you want to re-do it every year or so.

Is @JeepVet74 the only one that's experiencing this issue? It seems like there are lots of suggestions on how to reduce the associated heat, but I haven't seen posts from others that are in the same boat. It's not even June yet.

I think I figured out what’s going on with mine. I drove it home 2 hours in the hot sun and then drove 5-10 solid minutes straight up our mountain. That, plus the rubber mat on the passenger seat floor acting as an insulator, plus I had an insulated soft-sided lunch cooler sitting right on top of it, made the mat feel really hot. I’ve been checking that mat every time I drive it now and no issues. Not even warm to the touch.
I don’t think there’s an issue but I’ll continue to obsess over it bc that’s who I am. Lol

Nothing wrong with obsessing over it, maybe just take mat out drive and see how it feels on the carpet?

Cool stuff though I grew up in Red Bank, Signal mountain was cool back then we would repel up there before it got built up like it is now. Bonfire parties in Dunlap was not unusual :)

That’s a great idea. I may do that next time I drive home from Atlanta in the hot sun and then up our mountain. Want to see how it feels without the mat in it.
My first job as a small animal vet was working at the animal hospital in Red Bank. Such a cute area! We live on the back side of Signal (away from the bourgeois) ?. Short trip and we’re in Dunlap. Man that area is gorgeous!

I'm not sure this is a problem but just wanting to check with other 392 owners. I drove back from Atlanta this evening (2 hour drive). Easy drive. Ended with a drive up our mountain. Got home and touched the passenger side floor board and that thing was hot! I have rubber Weather Tech mats so I thought maybe the rubber acted as a conductor and made it feel hotter than it really was. But I could barely hold my hand on the mat. No warning lights or anything on the way home.
Anyone else notice this with their 392? Is this normal or is there a problem about to manifest? We're hoping to take this on a 7 hour ride to Florida next month and I'd hate to be stranded somewhere on the way down. Especially somewhere in Alabama :LOL: (I'm just kidding- I lived there for 10 years).
So just for future notes. Rubber has one of the lowest coefficients of thermal conductivity. That goes for heating and cooling. It usually stinks pretty bad before it goes soft. Within reason, its a decent insulator, so long as its not in direct contact with something glowing. Your issue is reflected heat from the exhaust system. I see the same issue. While it may be a less that perfect design issue, it is probably not a worry. I had a 67- 427 L88 Vette that would actually burn bare feet on the foot well. Progress!! American Junk has come a long way and I am a big supporter. I buy it!
