Cleetus’ Big Block Swapped Crown Vic – Dyno and First Burnout

May 12th, 2022

Cleetus McFarland and his crew at Freedom Garage are known for building some wild rides. None is wilder than the Twisted Tea Ford Crown Victoria. Saying this car has undergone weight reduction treatment is like saying a pig’s behind is pork. This car has been decapitated and stripped down to the bare necessities.

As if that weren’t enough, these guys trashed the old modular 4.6-liter engine and replaced it with a massive 632 cubic-inch big block. This is an all-aluminum, dry sump behemoth of a motor that is capable of producing 1,000 naturally aspirated horsepower (on race gas). Running pump gas, it should be good for 800hp at the crankshaft. Today, we get to see what kind of power this crazy contraption can put on the pavement. It’s dyno time!

Right out of the gate, Cleetus knows there is a fuel problem. He can’t get the air/fuel ratio into specs. Nevertheless, the guys perform the first dyno hit to get a baseline. Even with insufficient fuel, the car dynos 577whp. Not too bad, but it can get much better.

Turns out that an incorrect fuel pump was installed and it needed to be replaced. With the fuel supply issue resolved, the Twisted Tea Ford went on to dyno 715whp (875 lb.-ft. of torque) numbers consistently. This thing is a beast! Just wait until he turns on the nitrous!

The dyno testing is done. All that’s left is to hit the parking lot and pop some tires.
