1974 Ford Bronco - Brand Loyalty

What is it about Green Broncos running Chevy parts? We ran a feature on Chuck Diesel’s LS1-powered Bronco in our Sept. ’13 issue (“Blasphemy!”) and received a lot of hate mail from both Chevy and Ford fans as a result. Marc Letourneau hasn’t strayed as far from the Blue Oval as Chuck did, but Marc is running a Corporate 14-bolt under the rear of his Bronco. Why? “The 14-bolt is strong, simple, and cheap,” Marc states matter-of-factly. The eight-lug bolt pattern and width also make the 14-bolt a great match with the Ford Dana 60 front axle that Marc slung under his Bronco. As for the powerplant, Blue Oval fanatics can breathe a sigh of relief. Marc’s Early Bronco is powered by a fire-breathing 396ci Windsor engine that churns out over 400 lb-ft of torque.

Blue Oval fanatics can breathe a sigh of relief.
The cage is a combination of parts from Wild Horses in the front and custom fabrication in the rear for a unique look that remains functional. Under the cage, the occupants are contained in Mastercraft Baja RS suspension seats with MasterCraft safety harnesses. A Tuffy console sits between the seats while an aluminum RCI fuel cell is securely fastened in the cargo area with Artec brackets.

Power comes from a 396ci stroker from Motor Works topped with Mustang fuel injection. The Windsor block uses an Eagle crank and hypereutectic pistons with a flat tappet camshaft and iron cylinder heads, and it runs fine on pump gas. Sharing space with the V-8 engine are the ARB air compressor, hydroboost brake setup, PSC steering reservoir, and Optima RedTop battery.

The simplicity and lack of plastic makes it easy to see why Early Broncos are so popular. Marc added a Sony marine stereo and a Flaming River steering column to the otherwise factory dash. The offset shifter for the NP435 is from Wild Horses, and the trio of short shift levers control the NP203 and the twin-stick Dana 20. Toyotas have nothing on this Bronco!
