1969 Mustang
The Mach40

Regular readers will recognize the Mach40 from our Top Cars of SEMA 2012 coverage last year. Typically we look for unique cars in our event coverage, but we felt Dave Eckert of Eckert's Rod & Custom and the Mach40's owner deserved recognition for having the courage to not only accept the OUSCI invite, but to run a seven-figure build hard. Built as an interpretation of what a 1969 Mach1 Mustang would look like if it had been the basis for Ford's GT40 racers, the mid-engine, GT-powered Mach had the pedigree for sure. It has spent significant time on the street getting sorted since last year, but OUSCI would be its first competitive outing.

Eckert told us from the beginning he's not a racer, but out on the autocross and road course he drove the Mach40 impressively hard—hard enough to put it in the dirt once. Picture it and cringe: that car, sliding off track into the dirt. Other than that slip, the Mach40 looked stable, well balanced, and positively gorgeous as it rounded the corners and hit triple digits on the straightaways.

But that's what this amazing feat of metalwork and engineering was all about from the beginning: It was never intended to be a trailered, pampered show car. The owner drives it to work regularly, and was eager to see its capabilities on track. Now Eckert has some additional data to put into adjustments for the suspension.

1972 Pantera
Pro Pantera

When Bob Benson picked up this 1972 Pantera 13 years ago, it already had a history of autocrossing early in its years, and was later set up for mild open tracking. But Benson says it really was not that fast and was more of a show car, so he spent most of his track time in his 1965 GT350R clone. That is until he over-revved and scattered the 347 stroker on the front straight of Thunderhill. Benson bought a new 302 block and was starting to do a 331 stroker replacement, but his Pantera buddies bugged him so badly that he decided to do a motor for the Pantera instead. So he sold the 302 and bought a 351 Windsor and stroked it to 411 inches.

Benson pulled the factory Cleveland, had the engine bay detailed and installed the engine with 180-degree headers, chassis braces, a four-point rollcage, custom Fuel Safe cell, full MSD ignition, Wilwood brakes, and some sticky Hoosier R6 race tires. The first time he tracked the car, Benson won his class and beat many full race cars with his street-legal ride. "I told my wife the car was a lot better than the Mustang," Benson said, "and that was a really good car."

So far, the Pantera has been raced yearly at the Pantera Club Event, as well as autocrossed, drag raced, and driven to Vegas and back on Hoosier R6s. It has run at Reno/Fernly, Thunderhill (Checkered Flag racing), Sears Point (Infineon), Laguna Seca, Firebird Raceway, and even Spring Mountain in Pahrump. So really the biggest challenge for Benson at OUSCI was learning how the Pantera would handle on the required 200-treadwear tires rather than full-race rubber. By all indications, it did quite well.
