Art and Mary Krepps’ 1961 Corvette
Art Krepps built his 1961 Corvette with one hand tied behind his back. Well, maybe we’re exaggerating just a bit. But he did bring the ’Vette from backyard trash to a showstopper himself, with help from his sons. That includes fabrication, body work, paint, engine work, interior, and anything else custom the car needed.
It just goes to show you that if you want something done right, you gotta do it yourself. From the big-as-life BDS 8-71 supercharger sticking up out of the hood to the stock-appearing body and interior and five-inch exhaust tips that peek out in front of the rear tires, the Vette is an all-around awesome car.
“Most people have a list of shops that did the body work, paint, and fabrication,” Art said. “Doing that work myself was the most rewarding part of the project. I put a lot of hard work into making it just the way I wanted it. I had a good idea of the engine this car would have so I built everything as strong as possible. And except for being tubbed and having a blower sticking out of the hood, it still looks original.”
The Corvette started out like so many cars—as an “empty nest” project. After Art and his wife Mary raised their two sons, the high performance bug came back with a vengeance. Art was preparing a motor and transmission for a 1974 Corvette, but both he and Mary were quite fond of the 1961 body style. He found just what he was looking for: a raggedy ’61 that needed some attention in a bad way.
Not that there weren’t accomodations that needed to be made for the car.
“He kicked me out of my spot in the garage, but that didn’t last long,” Mary said. “Soon he built a bay-and-a-half addition just for the project. He had plenty of room and I got my parking spot back.”
Wise move there, Art.
A concrete contractor by trade (A.C. Krepps & Son Concrete Contracting), Art happens to have a lot of free time during the cold winter months in Pennsylvania. In the three years he spent working on the car, Art backhalved the frame, replaced the front end, fabricated the trunk, and radiator mounts, and cut an access hole in the hood that perfectly follows the supercharger’s lines.
When you peek under that hood, a L88 427 with a pair of Larson two-piece valve covers will stare back at you.
“I get a lot of people who think [the valve covers] are the cylinder heads because they’re so big,” Art said. “People have offered to buy them, but I’m not giving ’em up—I’ve only seen one other set.”
The supercharged L88 puts out an estimated 850 horsepower at 6,000 rpm. Art needed an exhaust system that wouldn’t rob any power, so he he fabbed a system from a pair of four-inch diesel truck mufflers, Car Chemistry inserts, and five-inch exhaust outlets. The no-nonsense, stovepipe black finish keeps the big pipes from looking too obvious and detracting from the Corvette’s body lines.
In his mission to keep the car as close to stock as possible, Art didn’t cut up the dashboard to fit the Auto Meter Pro-Comp gauges. He made a custom console that simply slips over the original center console and holds the gauges in an easy-to-read spot. He also recovered the seats so they’re look like newer, cleaner versions of the factory originals.
Between the local car shows and cruising with one of the two clubs they belong to (The Cruizin Few and Corvettes of PA), Art and Mary put about 500 miles on the Corvette every year.
And when the neighbor’s windows start to rattle, everybody knows the Krepps are home.
