Four hundred and fifty-five cubic inches is almost 7.5 liters, which is how much fuel this thing will drink every time you start it up. OK, that's an exaggeration, but this iron behemoth is otherworldly compared to today's turbocharged 4-cylinders that can make as much power (the 455 was rated between 200 - 400 hp SAE gross, which would be considerably less as measured by today's net standards, with accessories and stock manifolds, etc). The 455 was an option in the Cutlass, just not this particular wagon originally. GM even used it in the FWD GMC Motorhome - hey, all of that road-hugging weight was good for keeping traction over the driven tires.
