Yes. A friend took his carpet out of his YJ I think it was and it had a "caution hot" sticker on the tunnel. You might still want to double check for an exhaust leak in the area blowing at the floor, but....

Mine got really hot from the exhaust being to close without a heat shield. I will be building a heat shield myself but I did see one on Power Nation tv cant remember what program though. It was a bolt on product for tight areas.

Interesting. I put carpet in with 'fireproof' insulation and it helped a ton. There is just one area where I ran out of insulation and I dont want to melt my carpet haha. Maybe I worry too much.

My floor at rear passengers feet gets so hot that the drain plug has started to melt! You can't hold your hand on the floor for more than a second but muffler looks to be 3-4 inches from floor. Any ideas?

Go to your local street maintenance yard and see if they have 3-4 "No parking" signs. Most times, they'll just give'em to you--
They make great heat shields for above the 'cat' and muffler.

That is way too hot! When that happened to our Cherokee, one plug was dead pouring raw gas through the system that caught fire in the cat and muffler. They were cherry red.

I have also seen small leaks that pointed at the floor causing real hot spots.

My tub is fibreglass, it would never stand that kind of heat. No heat shields on it either.

There were several heat shields installed from the factory on Jeeps and 1983 probably has the same amount as my 84.

There's a shield welded to the tub firewall to keep heat off your feet and another heat shield welded to the bottom of the tub at the rear passenger area. Plus, heat shield for the CAT and another mounted on top of the muffler.

You now have a Chevy 350 with headers and dual exhaust I imagine, so you will get more heat and would need to install your own custom heat shields.

When I had my 76 CJ-5 with 304, I ran a set of outside frame headers. One day it got hot enough to discharge a can of tire inflator sealer I kept under the driver's seat. Went of with a loud hiss.

On my 5 I used to have I used header wrap on the exhaust where it came close to the floor and got hot. Kinda looked like a mummy after a couple of years,but worked out well.

I went to home depot and got a 3'x3' sheet of aluminum that I folded in half to make thicker, when I have time I am going to use that as additional heat sheilding between the mufflers and tub.

I've put leftover pizza, in the box, behind the driver's seat, under the carpet. It heats up real well there for trail ride snacks.
