Here is a pic I took of my family's '74 Cadillac Coupe de Ville. 472 engine, completely stock.
I poured some water on the ground and asked a friend to drive (because he can't take good photos).
He told me that as he was nearing the top of the hill, he actually let of the gas- the tire was still spinning!
Anyway, pretty good for a anti-smog-device engine with only 8.25 compression ratio.
