Step 2 - Choose The Right 355 Cubic Inch
American Speed’s Dyno Tuned Hi-Performance Chevy Engines are custom built with the best possible parts at the best possible price to deliver the most driveable performance possible. Every engine from 275 hp and up is dyno tested, tuned and broken in before shipping. If you order one of our carburetors or ignition systems they will be set up and dyno tuned on your engine. Our efforts on the dyno can save you countless hours of headaches and guessing trying to tune your engine. We believe every customer should get the actual horsepower, performance and driveability they are paying for whether it’s a hi-performance street engine or a blown race engine. We don’t Sim Test or ”Run Engines In.” We actually dynometer test every engine under a load to verify actual horsepower, torque, reliability and thoroughly check engine for leaks and irregularities. Actual dyno testing will pin point any problems before they can occur. American Speed guarantees horsepower figures to within 1% of advertised. Every customer gets a computer printout of their engines performance. American Speed offers you more real value and performance for your dollar. Carbureted, fuel injected Turn Key engines are available.

All engines are sold as ”long blocks” complete from intake manifold to oil pan. Accessories are extra cost.
