About Us | A.H.M. Performance | Engine Rebuilds & Performance Machining

Company History

For over four decades, A.H.M. Performance has been a trusted name in engine machining, rebuilding, and performance enhancements. Founded in 1979, we started as a small engine machine shop dedicated to precision craftsmanship and high-performance engineering. Over the years, we've expanded into a

full-service engine machine shop, specializing in custom racing engines, restorations, and high-performance modifications.


From classic muscle cars and vintage restorations to modern performance builds, we have worked on Chevy, Ford, Nissan, Toyota, Honda, AMC, Buick, Oldsmobile, Pontiac, and many more. Our reputation for quality, precision, and innovation has made us a go-to destination for performance enthusiasts, street racers, and professional track builders.



Whether you need a full engine rebuild, performance upgrades, or precision machining, we take pride in delivering unmatched craftsmanship and superior engine performance.
