Glenn Landrum's story starts out like many others: guy likes cars, goes into the Marines for eight years, gets married, and buys a '98 Camaro Z28 (which he modifies here and there while raising a family). But wait, our story is about his other Camaro-the '95 Camaro Z28 race car he and his good friend Mitch Warren built to compete in the Camaro Mustang Challenge Series. The what series?, you might ask. Keep reading.

Glenn originally bought his '98 Z28 for autocrossing, open track racing, drag racing, and all around fun. Over time, he found that he was drawn to open track racing more than anything else, sinceit allowed him to race against other cars on acclaimed road courses like Texas World and Texas Motor Speedways. Glenn was able to race on major tracks like these by participating in the National Auto Sport Association's High Performance Driver's Education classes, which are held during their racing events to help novices get seat time in wheel-to-wheel racing. He attended HPDE classes, moving up through all four levels and earning his competition license. Right when the learning curve was tapering off and Glenn was looking for a greater challenge, he came across the Camaro Mustang Challenge series. This series looked like it would satisfy his desire to race competitively in the Fourth Gen F-body style with which he was familiar. Since the class utilizes essentially stock powertrains, the emphasis is on driver ability-not the size of your bank account. While the decision to construct a purpose-built race car was a leap for Glenn, it also enabled him to save his sano '98 Z28 from potentially getting stuffed into a race track wall.

Despite the nay-saying of friends, Glenn forged on and bought the shell of a '95 Z28, which was so stripped he had to use a jack to get it onto the trailer. A '93 Z28 in a bone yard yielded up an 80,000-mile stock long-block, computer, and other needed parts. Since this is a track-only car, all of the factory wiring was removed and Glenn swapped in a Painless engine control harness, finishing the other wiring on his own. Also removed was all non-essential sheetmetal and bracketry, as well as a seam sealer and sound deadener, in an effort to get the car down to the class minimum of 3,200 race-weight. Even with the comprehensive eight-point, mild steel rollcage that was welded up, the car was still 2,950 pounds dry (without driver). While this lightweight, 285 rear-wheel horsepower beast was ready to rumble, the class limits Fourth Gen F-Bodies to 230 rear-wheel horsepower and 300 rear-wheel torque, so #70 runs a restrictor plate. (NASA enforces the power limit by having racers dyno their cars on a random basis.)

This series originated out west, and debuted in the Texas region in 2004. Glenn was in "recon mode" during the short 2004 inaugural racing season, as he was not yet ready to campaign the car. The following season, he showed up at the first event, and ran the car during a pre-race test session. His testing was cut short when a Cobra replica in front of him spun out and he T-boned it. Never the kind to sit around, Glenn, his brother Brandon, Greg Hoffa, and Mitch Warren tore the car down and realized that they could get it back together in time for the race the next morning. This all-nighter resulted in a front end cobbled together with borrowed sheetmetal; but when he pulled into the pits the next morning, the other racers gave him a standing ovation-proof positive that the thrash had been worthwhile.

In his rookie season, Glen piloted #70 to Fifth place in points in the Texas region, racing in a 15-car field and winning more than any other rookie in 2005. The LAW Motorsports #70 returned in 2006, placing Second in a larger 23-car field. Glenn and Mitch made the long haul to the First Annual NASA National Championships, held at Mid Ohio in September 2006, where Glenn navigated #70 through an intensely competitive 24-car field to finish Third.

With the 2007 season already underway, Glenn is out there racing #70 with a freshened long-block and a personal goal to win this year's championship. Many have helped over the last few years, but Glenn particularly credits his wife Tami, their two daughters, his racing teammate Mitch Warren, and his sponsors Argent Lab Radios, Moonlite Printing & Graphics, Natwell Supply Corporation, and Performance Speedtech for their outstanding support. He also cites LG Motorsports as a major influence: "Lou not only helped me get the car class ready and let me use some of his facilities off-hours, but he also gave me a lot of invaluable advice about racing setup and prep." Additionally, Mike Patterson of SCCA T2 fame is owed a great deal for passing on his track strategy experience, or "the chess game of racing." Glenn shared that he has typically raced a full season with the same set of plugs and wires, using about three sets of brake pads and two to three sets of tires per season, dispelling the myth that track racing always requires a ton of thrashing and parts. "Running at the restricted 230 rear-wheel horsepower level keeps these cars from breaking a lot of parts, and makes it an affordable class," says Glenn. He likes to visit,, He encourages anyone interested in the series to check it out, as it has expanded across the US. Since LAW Motorsports has prepared a few cars for other racers, Glenn is confident that a competitive car can be built for slightly more than $5,000. "I have about $10,000 in #70, but that's because I spent more on the bling than most others." Fellow racers: keep an eye out for Glenn Landrum in 2007-he's looking for the winner's circle at the Nationals.
