Introducing the Texas Speed In-Stock Short-block program. The goal of this project is to provide
customers with quicker product delivery without the extended build times. By offering a variety of
common engine designations and compression choices, the customer will have an option that is ready to
ship out in a few days. The same parts, machining, care and workmanship goes into these builds using
the exact same processes as our custom engine program. The only difference is that the engines are pre-built before purchase instead of the build process starting after purchase. All engines are balanced,
blueprinted and assembled in house, to exacting TSP tolerances.
