I asked on one of the Facebook posts about the vette's weight and was told it was nearly 3500 lbs if I recall correctly. I find that hard to believe.
I know they aren't as light as some think, but still....it's a fiberglass body w/ aluminum heads, aluminum intake, lightweight brakes, etc. There's no way it's as heavy as a hemi E body.
It does have an 8.50 cage in it but I would be hard pressed to believe its 3500 unless that is including the driver , the base curb weight of the 67 coupe is 3140lbs .
I did find this on a corvette site
