1967 was the last year for the Cadillac 429cid V8. For 1968 the 340bhp 429 was replaced by the new 472 cubic inch engine rated at 375 SAE gross horsepower. Those were big motors, but this is a nearly nineteen foot long car that weighs almost every bit of two and a half tons. (And the next generation would be even bigger. Downsizing didn't hit the DeVille until the '77 model year.)
