Chevy Engines - Crate Engines- Racing Engines- Big Block Engines

Welcome to American Speed Enterprises home of the Chevy high performance engine. When it comes to Chevrolet racing engines, the 350 Chevy engine, or just about any type of GM crate engine we can build it and most likely have built one before. Our professional staff of engine builders takes pride and stakes their reputation on every Chevy high performance engine we build. When you purchase an American Speed built Chevy stroker engine, you're buying over 35 years of experience in building not only just Chevrolet engines, but also a vast experience in building every street rod engine and American muscle car engine ever produced by Chevrolet. We don't mass-produce our Chevy crate engines but custom build them one at a time with your application in mind. Our secret to the power, quality, and reliability in our Chevy high performance motors is using the best combination of parts in every Chevy engine we build with complete control of every phase of construction.  We stand behind our guarantee and Warranty Information.
