We Put a 533HP 460 Big Block in an Old F-150—Then Took It Off-Road

We took a bone stock OBS F-150 and transformed it into an off-road beast we call Leadfoot, built as a tribute to the legendary Bigfoot, the original monster truck. We started by stripping it to the frame and dropping in a massive 460 Big Block, which required custom motor mounts and serious frame boxing to handle the torque. We gave it that classic monster truck stance with a 6-inch BDS lift and 35-inch Super Swamper tires, then moved inside to fabricate a custom roll cage and a one of a kind aluminum gauge cluster. From the custom-built cold air intake to an exhaust that sounds like a World War II fighter plane, we built this truck for pure fun on the trails. Stick around to see us give it a trial by fire at the off-road park! PARTS USED IN THIS EPISODE EBC Brakes EBC GD Sports Rotors https://pntv.us/pn_pt_25203_6824b5f78...
