1971 Ford Bronco - Bought Bronco

Posted in Features on November 17, 2014

Zach Oberlander works with cars all day at his business, Autobahn Automotive. So understandably, the last thing that he wants to do in his free time is spin wrenches. Instead Zach keeps an eye out for good deals on cars, boats, and 4x4s that someone else has already put the time and money into. His latest purchase was this ’71 Bronco, which was originally built by Nick Vona. When the racing bug bit Nick, he traded the Bronco to Travis Carpenter for Carpenter’s Ultra4 buggy. However, Travis was looking to start a business and didn’t have the Bronco long before Zach scooped it up. “He handed me a stack of receipts that totaled over $10,000 for the engine alone!” Zach recalls.

The Wild Horses half-door inserts work with soft half-doors and the full Bestop soft top. They allow great visibility on the trail and match the body lines of the Bronco much better than the square openings when the factory full doors are removed.

The money was used to build a stout 347ci stroker engine. Tony Hews of Hews Performance built the small-block Ford with a Scat forged rotating assembling, AFR 185 aluminum heads, and a Comp Cam camshaft and roller rockers to produce an estimated 450 hp. The engine is topped by a FAST fuel-injection system that allows it to operate at any elevation and any angle on the trail. Of course, there is more to this Bronco than just the engine, and the rest of the drivetrain is just as impressive. A bulletproof NP435 transmission routes power to the dual T-cases, consisting of an NP203 range box mated to the factory Dana 20 using components from Advance Adapters. The axles are still a high-pinion Dana 44 in front and a Ford 9-inch in the rear, but they have been upgraded in every way imaginable. The front uses a larger Dana 50 ring gear from Jantz Engineering around an ARB Air Locker with RCV chromoly axleshafts tossed into the mix. Out back, 35-spline chromoly axleshafts from Moser and a Detroit Locker are more than enough to reliably handle the 38-inch-tall Goodyear MT/Rs.

While his friends are in the garage throwing wrenches, Zach is enjoying his ‘bought Bronco.

The Goodyears stay in contact with the ground in nearly all conditions thanks to the custom suspension from Silly Fab Service (SFS) in Rancho Cordova, California. Phil Licciardi of SFS extended the front radius arms with DOM tubing and rod ends to allow for more wheeltravel, less camber change as the suspension cycles, and less binding with the Wild Horses coil springs and Fox 2.0 shocks. Out back, the leaf springs were ditched in favor of a coil suspension that uses very similar components to the front for balanced articulation on the trail. The same coil springs and Fox shocks are used in the rear, but without steering to worry about, SFS was able to build a triangulated four-link to locate the 9-inch axle. Using a triangulated suspension in front was not an option with the traditional steering box and crossover steering, as the suspension would cycle in a different plane than the drag link, resulting in massive bumpsteer. That was not recommended on the trail, and it definitely would not work on a rig like this that sees the pavement as well. There is an old adage that “real rigs are built, not bought,” but if you want to hit the trails tomorrow and can save money over buying parts new, it is hard to argue against buying a built rig. While his friends are in the garage throwing wrenches, Zach is out enjoying his “bought” Bronco.

Power comes from a potent 347ci stroker with a forged Scat rotating assembly and AFR 185 heads. Under the K&N filter, a FAST fuel-injection system provides the mixture, while the Mallory billet distributor and wires light the fire. Note how the inner fenders have been lowered to provide more room for the dual Optima RedTop batteries and the ARB twin compressor.
