Benefits of an AMS Built Long Block Engine:
Every AMS engine is individually handcrafted with the same care and precision as those in our world-renowned race cars. When you select an AMS engine, you’re investing in over 20 years of knowledge from building thousands of high-performance engines. Each motor is carefully balanced, blueprinted, and assembled to meet our stringent specifications—just like our 3000+ WHP race cars. Before the build begins, we inspect every block for critical factors like cylinder bore accuracy, block flatness, and main alignment to guarantee a strong foundation for your engine. We also maintain an archived spec sheet for every engine, logging tolerances, torque specs, and clearances to ensure consistent quality.
