When you think of Olds' most powerful autos, at least in the 60s, were the Toranado and the 442. Oldsmobile spare no expense when coming to power with these 2 cars. I think the 455 HO engine was standard with the Toronado. What made it unique was the front wheel drive, which is was rare then. I think the Caddy Eldorado was the only other one to have it (hey they ryhme).
It got real, real ugly in the mid 70s, like all other cars and became a POS. In its day, it was one mean machine.
