Nothing beats cubic inches and stroke when it comes to upgrading your LS engine! If you are looking for proven performance from a professional engine shop then you have landed at the right place - the SDPC Raceshop LS short blocks and engines are built using the latest Rottler CNC block machining center and the Rottler H75X CNC vertical hone for a race prepared blueprinted block and a computer controlled cylinder bore finish that is normally only found in professional racing engines. The crank, connecting rods, rings and bearings are precision matched and balanced on the latest CWT balancer to insure a vibration free rotating assembly for fast throttle response and proven durability. All clearances are precisely measured and recorded to each serial numbered assembly.Before any parts can be installed in one of our engine and short block programs, all components are thoroughly evaluated and tested in our SuperFlow Powermark 902 dyno room testing facility. You can count on proven performance and durability from actual testing of parts at the SDPC Raceshop. The Raceshop Team has over 150-years of engine assembly, testing and racing experience. Professional experience you can depend on when your short block and engine is assembled in the SDPC Raceshop.
