Pretty sure they have off the shelf stuff as well. My engine has AFR aluminum heads, headers, AED Holley carb, and MSD ignition. Runs on 92 octane unleaded and Dyno'ed at 413 HP. Loved those 80-81 Z28's when they came out. My first car was a brand new 1980 Camaro LT with a 305 4 speed. Loved that car until I wrapped it around the front of a full sized Ford station wagon.
