Welcome to BBJ Automotive Cores, Inc. After 25 years experience in the Core business working in a family business and the corporate world I ventured out on my own and started BBJ in 2010 selling used Carbs, Intakes, Valve Covers as well as Blocks, Heads and Cranks for early V8 engines, But as times have changed and the New Chevy GenIII/LS engines have become the choice of performance enthusiast we have expanded our line of products to not only include used parts for these engines but also a full line of new engine parts for the GENIII/LS engines. At BBJ we are your AFFORDABLE parts source for GENIII/LS engines.
