All of our built engines are individually handcrafted at AMS using the same care as the ones found in our world record setting race cars. When you choose an AMS engine you are investing in the knowledge gained from assembling thousands of race engines over the past 20+ years. Just like in our 3000+ WHP race cars, every motor is balanced, blueprinted and assembled to our precise specifications. Before assembly each block is checked for correct dimensions, cylinder bore, main alignment, block flatness, and more to ensure you get the best foundation for your new engine. Every engine we assemble has an archived spec sheet where tolerances, torque specs, and clearances are documented as part of our standard quality control process.
