If you recall from last month, High Performance Pontiac invited a group of drag racers from across the United States to arrive in Norwalk, Ohio, the day preceding the Ames Performance Tri-Power Pontiac Nationals. Their mission: attend our Pavement Pounders Shootout, get the opportunity to see their cars in HPP magazine, test and tune their combos, have fun on the quarter-mile track, work on launch techniques and shift-point strategies, and acclimate their cars to the Summit Motorsports track in a relaxed environment-in contrast to the fiercely competitive Pontiac Nationals race program, which follows our event.
For our second installment, we compare two vintage '60s Pontiac coupes-a stock-appearing A-body and a radical-looking, lightweight G-body.
Paul Glasgo of Green, Ohio, is an automobile restorer who specializes in stock-appearing muscle-cars. There's no wonder that Pontiac is his favorite brand. His '67 Ram Air GTO features a 400 with No. 670 heads, a Turbo 400, and 3.90 gears.
Glenn Sedig of Sterling, Illinois, is the owner of Vintage Mechanical Works Auto Restoration. When he's not restoring customers' Pontiacs for the street, the track, or both, you can find him out on the track with his race-only '69 GP. It features an IA II 473ci engine, Tiger High Port heads, a Turbo 400, and 4.88 gears.
The temperature at Summit Motorsports Park during our Shootout ranged from 78.5 to 88.2 degrees. Barometric pressure was measured at 29.74 hg and the dew point was 72.6 degrees. The track is 853 feet above sea level and density altitude ranged from 2,424 to 3,245 feet. This month, both racers' best passes of the day occurred with a density altitude of 3,100 feet, so they'll receive an altitude-correction factor of 0.9627 for e.t. and 1.0395 for mph. 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.
