'73-'77 Chevelle Engines and Accessories
For your car's performance LSX engine needs, Speedtech Performance has teamed up with Texas Speed and Performance (TSP) to provide a winning combination of experience, quality, and serious horsepower. TSP is now one of the largest high performance parts retailers in the country specializing in the late model LSX engine. With over 30+ combined years of experience specific to the LSX market, you can be assured you will be provided with the expert knowledge and technical expertise you need in a well built LS engine combination.
Texas Speed engines come in "turn key" kit form meaning they are designed to provide our customers with a true drop-in engine that is ready to run! Every TSP engine is hand-assembled and all machining and assembly, as well as cylinder head production, is in-house and NOT sourced out. All components in TSP engines are brand new parts, including the block, so you are not buying an engine that uses any remanufactured items. Texas Speed is the only LSX-based company that digitizes and blueprints every engine block on a CNC machine to the factory GM specifications.
Below are listed 3 of our more popular applications. There are several additional options for these packages as well as other complete engine packages available, including LS1, LS2, LS3, LQ9, LS7, LSA, LS9 and LSX based engines. Please call our sales department at 1-435-628-4300 to get more info about an engine package that meets your specific needs.
