BASELINE PARTS LISTLike many 10-year-old Z28 Camaros, ours also had a complement of bolt-on performance parts that it had accumulated over the years. The following parts were already on our test car when our baseline dyno test was performed. Some of the items listed have a direct bearing on the power output to the rear wheels (such as the exhaust and cold-air package) while other items have an impact only on the street or at the track (such as gears, wheels/tires, differential, or shift kit). With the exception of the Holley throttle body airfoil, all the items listed were in place for the dyno test after the installation of the Edelbrock Performer LT1 package. It is worth noting that most people considering the Edelbrock Performer LT1 package will either have similar items or will get them soon. These basic bolt-ons are the low-lying fruit which should be harvested before any additional major mods are completed, and as you can tell, our stock-engine test car was ripe for the head and cam package.
