Pure Stock SeriesIt has been said that "the third time is the charm," and even though we had two rainouts at the track in Norwalk, Ohio, our third attempt at completing a Pure Stock Shootout was successful. After running four cars at the Ames Performance Tri-Power Pontiac Nationals the day after the second rainout, the remaining group competed at Mid-Michigan Motorplex in bucolic Stanton, Michigan, just prior to the annual Pure Stock Muscle Car Drag Race (PS).
Mid-Michigan Motorplex is a first-class family-oriented facility with a paved pit area, a fenced-in playground for the kids, and lots of grassy sections to relax in during a race. It also has a great quarter-mile dragstrip. The staff was friendly and very accommodating as we ran a bunch of Pure Stockers through their paces, all in an effort to capture their exploits for these stories. For Part II of this Pure Stock series, we have an eclectic variety of Pontiac models and famed powerplants.
Weather ReportThe temperature at Mid-Michigan Motorplex rose from 55 to 71 degrees throughout the day. Humidity ranged from 41 to 100 percent and barometric pressure was 30.01 hg. Density altitude was 1,599 feet, so we will use a factor of 0.9822 for e.t. and 1.0185 for mph for 1,600 feet to chart the theoretical best performance at sea level. This will be done on the best pass only, based on e.t. Now let's get to the bias-ply burning action!
