1972 Ford Bronco Race Truck - Fast Ford

Yes, It Is My Daddy's Bronco

Grant Wilson works a fifth-generation family cattle ranch across 100-plus square miles of land northeast of Tucson, Arizona. He herds cattle for a living and drives fast across the desert for play. His go-fast vehicle of choice is a '72 Bronco with a valuable history. Grant's parents bought the Ford new some 35 years ago, and in 1993 he bought the 4WD in which he learned to drive at age 11. From there, he spent a lot of time desert running, but an error in judgment left the Bronco crumpled into a mesquite tree. Following that mishap, the truck was rebuilt and Grant started racing in organized events about 10 years ago. Since that time, he's managed to garner stacks of win plaques and trophies and is a five-time champion in the Whiplash Racing Sport Truck class. Additionally, he competes in a wide variety of desert, stadium, and Tough Truck competitions.

Grant recently replaced an older engine with a healthy Ford GT40 302 crate motor. A large K&N filter lets the engine breathe while keeping the dust out. The overall build of the truck is designed to be simple with maximum functionality.

Several years ago, the Bronco suffered a bad landing off a race jump and nosed into the dirt. The resulting impact cartwheeled the rig four times end over end. Grant survived thanks to a good cage, but the race truck was almost completely destroyed. However, a short time later, the Bronco was back in action with some additional improvements. All the bodywork from the doors forward has been replaced with fiberglass panels, and Metal Masters of Tucson shot the multicolored paint scheme.

Power for the Bronco comes from a Ford GT40 302 small-block crate motor and is set up with an MSD Digital-6 Plus ignition system so the engine timing can be adjusted as needed. Behind the lively motor, the factory three-speed tranny and transfer case still serve their duty well. Steering has been improved with a change to a Chevy Saginaw power steering pump and box. This combo maintains better pressure than the Ford unit did to ensure the steering stays precise. Somewhat amazingly, the Ford still comes to a halt with drum brakes on all four corners. Grant claims the throttle and a little tranny downshifting are about all he needs for racing.

A couple of KC lights have been added for the occasional night outing.

The front axle is a Dana 44 with James Duff heavy-duty special shafts, engaged using Warn hubs. The rear axle is a Ford 9-inch that's been upgraded with 33-spline shafts. Both axles house 4.11 gears spinning on spools. Grant admits that the dual spools make it harder to steer through tight stadium race corners, but the power to the ground is awesome. He's refined a point and throttle turning technique that gets the 93-inch-wheelbase truck around turns efficiently. Grant's tire of choice is usually a set of 33x12.5 Mickey Thompson Baja Claws wrapped on American Racing chrome spokes; however, sometimes BFG Mud-Terrains are used up front if increased steering traction is needed.

Living on a wide-open cattle ranch means there are plenty of desert roads to practice on, and Grant has a track area set up where he can drive fast and catch some serious air. This Bronco has a long family history, and it's still kicking up dust.

  • Normal fare on race rigs such as this are a pushbar up front and tube bumper in the rear, whether you're the fast one nudging a slower racer in front of you or getting tapped on the rear by an impending Trophy Truck. A Hi-Lift is tucked behind the bumper for desert repairs.

  • The custom rear cage protects the driver and navigator, supports a spare tire, and houses a 33-gallon steel fuel cell. It's good to have a quantity of gas on board as the V8 sucks down a gallon every 4 miles under race conditions.

  • The front suspension sports about 14 inches of travel thanks to a set of James Duff coil springs combined with Air Lift bags. The airbags can be adjusted on the fly from inside the cab. On rough course sections, they are left soft for maximum articulation and then firmed up for jumps or whoops as needed. James Duff also supplied the heavy-duty radius arms.

  • A Fox 2.5 reservoir shock and a Fox 2.0 shock keep the front end movement in check. Upper shock mounts are incorporated into the cage that runs through the engine compartment. Fox nitrogen bumpstops slow the axle compression that final bit to keep the truck from bottoming too roughly off the big jumps.

  • James Duff 11-leaf packs make up the rear suspension for the trussed Ford 9-inch. Damping for the 16 inches of travel is handled by Fox shocks. Grant runs two or three shocks in the rear depending on the course terrain.
