Photography by GRANT COXhe younger generation commonly refers to those who were around to witness the muscle car era of the ’60s and ’70s as “boomers,” slang for baby boomers, which comes from the high birth rate after World War II. Now, the term “boomer” is commonly used as a derogatory term coming from a typical Gen Z’er referring to one who is older or past his or her prime in life. Well, those young whippersnappers can learn a thing or two from a boomer, especially when it comes to vintage cars, as there is plenty of history to uncover and appreciate.
Michael Dorvillier is chairman of the La Jolla Concours d’Elegance so he spends a good amount of time surrounded by high-end sports and muscle cars, and he’s always had an attraction for the C1; in fact he was once an owner of a Heartland Customs (Purcell, Oklahoma) ’58 Stage I SPECVETTE—a Corvette Heartland Customs builds with modern performance and functionality while retaining the car’s vintage pedigree. “I’ve had many classic and exotic cars over the years and I absolutely loved that car, as it was hands down the nicest car I’ve ever owned, but while driving it one day a couple stopped me and asked if it was for sale,” Michael states. “Well, not to sound cliché, but they made me an offer I just couldn’t refuse.”
Under the hood went a Chevrolet Performance LS3 dressed in a set of original, custom-fitted Corvette small-block valve covers for a cool, vintage vibe. The LS inhales through a custom 4-inch mandrel-bent intake tube topped with a Spectre element and exhales through a set of stock exhaust manifolds onto a Heartland custom TIG-welded 2.5-inch stainless exhaust and QTP electronic cutout system. Borla ProXS mufflers give the C2 a throaty muscular tone. A Vintage Air Front Runner accessory drive system resides up front just behind the DeWitts aluminum radiator.
A Roadster Shop Fast Track IRS chassis resides underneath and features C7 spindles up front accompanied with a Detroit Speed rack-and-pinion steering system, Fox double-adjustable dampers, and 450-pound springs. Out back is a Fast Track IRS suspension system loaded with the same Fox shocks and 350-pound springs.
Inside the ’63 you’ll find a luxury performance scene featuring Moore and Giles Taupe leather throughout accented with Black Daytona carpet by Sculpt Garage out of San Marcos, Texas. The stock console and dash got the leather treatment as well and features Dakota Digital gauges with custom faces for pertinent operating info. Other custom bits include the CON2R black walnut steering wheel atop the Flaming River steering column.
Michael is a true fan of the iconic ’63 split window, but he just couldn’t shake the thought of that first ’58 SPECVETTE, so he’s still having Heartland build that car. “I’m looking forward to having my two favorite Corvettes done the way only Heartland Customs can,” Michael tells. “Having a classic Corvette handle like a modern sports car just doesn’t get any better.”
