Caballo Del Diablo: Budget-Friendly 1968 Ford Bronco Built For Vintage RacingPosted in Features on August 17, 2016 0) (
Boyd Jaynes of San Juan Capistrano, California, is typically on the working end of a camera and lens. However, after the first new NORRA 1000 rally in Mexico was announced in 2009, he began the search for a classic Bronco. The ’68 specimen you see was found on Craigslist in San Diego. Jaynes immediately secured the California license plate “MEX 1K” and went to work on the bobtail Bronco. The name Caballo Del Diablo quickly stuck, which is Spanish for horse of the devil.
Jaynes says, “The Bronco had no previous race history, but it looked racy.” The previous owner was a course volunteer at local desert races. Jaynes soon found out that the faux rollcage was not properly constructed or connected to the frame, so it was replaced with the current cage and shock mounts built by Jon Krellwitz at RDM Offroad. Since the cage build, Jamie Campbell at Raceco has done all fabrication.
The original transmission was a manual three-on-the-tree, which was replaced with a heavy-duty C4 with a manual valvebody from Steve Culhane in Lake Elsinore, California. In the spirit of racing in a vintage category, Jaynes has resisted the urge to modify the old Bronco’s suspension with a four-link, coilovers, or bypass shocks. Most of the suspension bits have been left in their original configuration, although they have been beefed up to handle a 1000-plus-mile race. The modern Fox smooth-body 2.0 shocks were professionally valved by Wayne Isrealan.
The engine is nothing special, and Jaynes claims it has just enough power to get into real trouble but mild enough to keep the drivetrain together. Jaynes says, “If you’ve ever gone more than 90 mph off-road in a short-wheelbase truck, like an early Bronco, then you know what I’m talking about.” The Bronco remains largely unchanged from the day he purchased it on Craigslist. Every inch of the original sheetmetal is still on the truck, although last year, Jaynes had to replace the hood for a lighter fiberglass version. The windshield is retained, which facilitates the use of old-school open face helmets and villain-like mustaches grown each year just for the rally.
After seven NORRA races, Jaynes and the Bronco have finished First in class four times, Third once, Fourth once, and DNF’d once with a transmission failure. He’s also placed as high as Eighth overall in the vintage category. At the 2016 NORRA Mexican 1000, Jaynes and the Bronco received the Steve McQueen Memorial Trophy for the fastest Pioneers-era vehicle of the race.
