Four months running, High Performance Pontiac has brought our readers the wild quarter-mile showdowns from our most recent Pavement Pounders Shootout, which we held at Summit Motorsports Park in Norwalk, Ohio, the day prior to the last year's Ames Performance Tri-Power Pontiac Nationals. Now it's time for another battle in this strip-scorching saga of Pontiac versus Pontiac. Let's meet the racers.

Doug Garrity of Tinley Park, Illinois, is a car-detailer by trade, but watch him really shine when he gets behind the wheel of his brother Mike's '79 Trans Am and terrorizes the track. It's powered by a punched 455, a Turbo 350 trans, and 3.42 gears.

Bret Blankemeyer of Pandora, Ohio, is a professional welder, but he trades his welding helmet for a racing helmet when it's time to wind up his '68 GTO and point it down the quarter-mile track. His Goat features a stroked 400/461 with Edelbrock heads, a Turbo 400, and 3.73 gears.

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. Bret's best pass occurred at 1:14 p.m. with a density altitude of 2,673 feet; Doug's best pass occurred at 2:41 p.m. with a density altitude of 2,906 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.

Doug Garrity

Doug (right), age 33, has been racing for 17 years. In 2011 he teamed up with his brother, Mike (left), to build the engine for Mike's '79 Trans Am. Since Mike now races their dad's (center), '701⁄2 Trans Am, Doug took over the driving duties on the '79. (Read about Mike Sr. and Mike Jr. in "Pavement Pounders Shootout, Summit Motorsports Park Edition, Part 2," Mar. '13). It's special to Doug because "It allowed my brother, dad, and me to go racing as a family again." He continues: "My favorite moment in the car is when our kids are in it. My brother Mike has two sons and I have one; the kids think it's awesome when we go ‘fast in the race car.' If they only knew we take it to the track and pull off 1.49 60-foot times!"
