Frequently Asked Questions

Engine Blocks

  • Do you provide reverse engineering for discontinued engine blocks?

    Absolutely. We offer reverse engineering services using 3D scanning and CAD modeling to recreate engine blocks for classic restorations, discontinued models, and custom builds with improved specifications over original designs. 

  • Can you handle both prototype and production engine blocks?

    Yes, we support complete development cycles from single prototype engine blocks for R&D testing to production runs of thousands of units. Our flexible systems scale efficiently while maintaining consistent quality across all volumes. 

  • What tolerances can you achieve for engine block cylinder bores?

    We routinely achieve tolerances of ±0.0005″ to ±0.002″ on cylinder bores, crankshaft journals, and deck surfaces. For racing applications, we maintain even tighter specifications down to ±0.0003″ using specialized tooling and inspection protocols. 

  • Which materials do you machine for automotive engine blocks?

    We machine aluminum alloys (A356, A380, 6061), gray cast iron (Class 30-40), ductile iron, and specialty steel alloys. Material selection depends on weight requirements, thermal properties, strength specifications, and application demands.
