Our Race Winning Experience Creates Higher Standards
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.
PRODUCT NOTES
- * Horsepower and torque numbers, and RPM limits are approximate and can vary significantly depending on numerous factors such as your turbocharger selection, intake and exhaust restriction/backpressure, and fuel octane and quality, among many others. The advertised numbers herein are based on optimal conditions and utilizing proper supporting modifications, but are generally attainable results by an average customer. Your results may vary.
- In rare cases, our component selection may vary from advertised based on supply chain delays. All component substitutions will be communicated in advance by your AMS Sales Representative during the engine assembly process.
- Assumes that a good condition core is sent in to build from. This requires a usable block and crank complete with engine girdle and oil squirters.
