This’ll kick the jonesing I’ve got going on. Scott Windle originally
posted about this particular Nova on novaresource.com last year, but I’m just now seeing it. It’s a 1970 Nova converted into a snowmobile by using three one-ton axles by a fella from Cedar City, Utah. To drive those three axles, he installed a 400-cu.in. small-block Chevrolet V-8 in the back and extended the body to cover the drivetrain. According to a failed online auction, the snowmobile was able to plow through 10 feet of snow at 45 mph.
What it’s doing on top of the shipping crate, though, I have no idea. I’d love to see some video of this thing in action.
