When I say that this car is a massive sleeper – I mean that it is huge. It’s a 1978 Cadillac Coupe de Ville and it is a big and heavy ride. This thing has all the bells and whistles but can a giant luxury coupe also be quick?

You can answer that question for yourself. Is a car that posts consistent 8-second elapsed times at 150 mph (quarter-mile) considered quick – in a word – yes.

This beast showed up at LS Fest with a professionally built 565 cubic-inch LS motor and a pair of turbochargers. I don’t know how much power this Caddy is capable of producing but it is plenty; even for this portly conveyance.

Even though this Coupe de Ville is painted a particularly putrid shade of beige, it has a certain aesthetic that is suited to a top tier street sleeper. This lead sled comes out of the hole like a champ and hooks up well throughout the 1320.

You just don’t see many Cadillacs with a parachute and drag slicks. This Cadillac is giving pimptastic a whole new meaning. You gotta see this one.
