If you thought Mopar’s 7.0-liter supercharged V8 Hellephant was the most insane powertrain available for wild engine swaps, think again: in Sweden, there’s a guy fitting a 27-liter V12 into a classic Ford Crown Victoria. Now that is an engine swap.

Dubbed the Meteor Interceptor by its creator, Daniel Werner, this Crown Victoria has the 27-liter Rolls-Royce Meteor V12 engine from a World War II-era tank. Werner had initially wanted to use the 37-liter Rolls-Royce Griffon engine of a Spitfire plane but ultimately ‘settled’ for this 27-liter unit.

As standard, this engine is good for 550 hp but for Werner, that’s not enough. In fact, he is equipping it with a pair of massive turbochargers and a custom ECU and is chasing 2,500 hp. The engine typically redlines at 3,000 rpm but work is underway to increase that to 4,000 rpm.

As you’d imagine, slotting a 27-liter engine into a Ford Crown Victoria is no easy feat. As such, Werner has fitted the front end of a Chevrolet C10 pickup truck to support the weight of the massive Rolls-Royce V12. This engine, by the way, weighs over 650 pounds and has also necessitated the fitment of a support frame that runs the entire length of the car’s chassis. Werner has also had to remove the windshield and cut the firewall to allow him to sit the Meteor engine as far back as possible.

The project is still in its early stages but the Swede’s ultimate goal is to hit 200 mph (320 km/h) in the car.
