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 Read More

This vs. That LS Swapped Subaru vs. 600HP Honda Civic Hatch

April 19th, 2022

We have a wild one tonight! Like two angry bumblebees fighting over a ripe honeysuckle, these two modified imports are planning to let it all hang out for the win. In the left lane, we have an LS swapped Subaru. In an effort to realize supreme domination by cubic inches, the factory boxter motor was scrapped for an LS V8 setup. After several V8 options were exhausted, the owner settled on an LS3 7.0-liter all-aluminum engine. He then added a kit of nitrous for good measure. A 6-speed manual transmission and a narrowed Ford 9-inch rear end complete the drivetrain. Read More

Going down a bit of a different path today as we take a look at a mud truck on steroids. I can’t imagine a gearhead that doesn’t enjoy an off-road adventure now and again.
