C3 Corvette floor change why?
Just curious as to why GM changed from the fibreglass floor in the earlier versions to steel? Was it just so they would rust out like all the other cars when the carpets got wet

the fiberglass has a 250lb weight limit as well....and road debris can and will find its way though the floor as well, not that car companies care about car safety until they are told they have to

The black book says...
"Engineers put a partial steel underbody in the forward section of Corvettes starting in '76 for added rigidity, weight reduction, & to better isolate the cockpit from heat generated by catalytic converters"

Just how much fiberglass had to be replaced by heavier steel to effect a weight reduction?

My 68 is a featherweight coming in at only 3500 lbs as a convertible when i had a small block in her. I expect now that she runs a big block, which is more steel she should be a bit lighter

Were there death reports of people driving along and suddenly falling through the floors of their '68-'75s and getting ripped to pieces?
I have 3 fiberglass ladders with weight limit warnings...maybe a previous owner of my '75 ripped off its weight limit warning label!

I looked it up years ago....remember in 1968 the average male wasnt the fat lazy pig we have all become....
In the 1960s, the average man weighed 166.3 pounds and stood at 68.3 inches (just over 5 feet 8 inches) tall.

I have to see if i can find the Heffer specifications...its been a while since i looked. My buddy was pushing maximum density so i wanted to be sure he didnt go through. There is no support under there on a 68, just metal seat track mounts on fiberglass

So where did you look it up? I REALLY need this information as I'm not sure if that's 250 per occupant or combined. At 165 lbs, I'm concerned that I may not be able to safely take on a passenger weighing more than 85 lbs! It gets worse if that includes the seat weight...myself and both seats would be right at that 250 lb limit.

It was 250 per seat. Since i bought the car ive added 15lbs atleast and i am 205 in my shorts. My buddy is 200lbs as well. I wouldnt worry about until you have to. I wish i could find it again. Its been 8 years since i found that info....i did find weights per seat for c6s and i believe it was 388 per seat

Back in the Fall of '78 in Ames IA. I got to drive around with the largest human to ever ride in my Vette.
Mike Stensrud, defensive lineman ISU and future Houston Oiler.
Mike was 6'ft 5" and around 300 pounds. Our shoulders touched...still the only person that's ever happened with.
I guess it's a good thing I had that steel floor...
