Welcome to High Performance Pontiac's Pavement Pounders Shootout, which we held at Summit Motor-sports Park in Norwalk, Ohio, the day prior to the Ames Performance Tri-Power Pontiac Nationals. As in previous installments, we hand-picked Pontiac racers from across the United States, invited them to the track, and told them to go to for their best e.t.'s ever. This month we bring you another action-packed round of Pontiac power versus Pontiac power. Let's meet the racers.

Gary "Marty" Atkins of Summitville, Indiana, is a GM assembly-plant worker, but what really gets him truckin' is putting his '66 LeMans on the track. It features a 400/406 with cast-iron D-port heads, a Turbo 350, and 3.90 gears.

Tom Scala of Warren, Ohio, is a steel-mill maintenance technician. His '68 GTO is powered by a 455/464 with Edelbrock heads, a Turbo 350, and 3.42 gears.

Both had high hopes of low e.t.'s, but found the day would be more challenging then they expected.

Weather Report


The temperature at Summit Motorsports Park ranged from 73 to 87 degrees. Barometric pressure was measured at 29.93 hg and the dew point was 57.9 degrees. The track is 853 feet above sea level and density altitude ranged from 2,177 to 3,073 feet. We give each racer his own correction factor based upon the density altitude at the time of his best pass. Gary's best pass occurred at 11:50 a.m. with a density altitude of 2,553 feet; Tom's best pass occurred at 3:21 p.m. with a density altitude of 3,073 feet. The correction factors are designed to chart the theoretical best performance at sea level and will be done on the best pass only, based on e.t.

Gary "Marty" Atkins Gary, at 46 years old, has been racing for five years. He acquired his '66 LeMans in 1983 because he liked its looks and Barrier Blue color. "My dad has known the car since it was new. A good friend of his bought it in 1966 and kept it until Dad got it from him in 1981," Gary says. His favorite moment in the car was way back in high school, when he "let three girls take turns driving it, while riding in the backseat with the other two." Gary also owns a '63 Tempest drag-car project and an '02 Grand Prix. He wants to thank Brent Flynn, Terry Spidel, and Brad Spidel (now deceased), for all their help in getting the most out of the combo.
