Many years ago I was riding in a 55 Buick that side swiped a tree at about 110 mph. The impact ripped the car in half. The back half remained at the tree and fortunately the front half with me and the driver continued for a block and and a half down the road and we had very minor injuries. If it had not ripped in half I would not be here today. On a side note I decided not to ride with Charley any more.
Those old cars can go, but the brakes are another story
My buddy had a 57 Chevy he put a modern Rat motor in but with original drum brakes, took two miles to stop from that kind of speed!
He should have got an anchor and threw it in the back seat until needed actually lol
