About Us

Engine on standAmerican Speed Enterprises builds the finest Chevy performance engines available anywhere. Our professional staff of engine builders take pride and stake their reputation on every engine we build. When you purchase an American Speed-built engine you’re buying over 35 years of experience in building and testing hi-performance and championship racing systems. We don’t mass produce engines but custom build them one at a time with your application in mind. Our secret to the power, quality, and reliability of every engine is our complete control of every phase of construction. For engine modifications and custom-built engines in Moline, Rock Island County, or Silvis, IL or Davenport and Bettendorf, IA, contact us today!

All machine work is performed in our own facility using the latest hi-performance technology available today. Every engine is fully blueprinted and balanced, individually machined and assembled. Our engines undergo a numerous series of assembly procedures before final assembly and dynoing. Every engine from 275 hp to 850 hp is dyno tested and tuned to insure power levels, reliability, and a controlled break in procedure.

Our goal is to build maximum performance and reliability into an engine that will give years of trouble free operation. A glance through our brochure gives a good indication of the power and the torque we make from our Chevrolet engines.

The highest quality parts are used throughout all our engines. This includes: new GM 4 bolt main blocks, selected sonic tested 4 bolt main re-conditioned blocks, Dart engine blocks, Speed Pro and Perfect Circle rings, TRW, JE, Manely, Mahle, and SRP pistons, ASE Super Stock rods, ASE 4340 H beam and I beam steel rods and Eagle rods, ASE, Comp Cams and Elgin camshafts, Crane, Comp cams, and PBM rocker arms, Fel Pro and SPM gaskets, Edelbrock intake manifolds, ASE, Eagle, Scat and Callies crankshafts, ACL, Clevite and Federal Mogul bearings, MSD and Mallory distributors and ignitions, Schuman and Mellings oil pumps, Canton and Stefs custom oil pans, Holley, Edelbrock, Demon carburetors, Air Flow Research, Edelbrock, Dart and Brodix cylinder heads, ASE, PBM, and ATI dampners, Accel wires and plugs, Hays and Mcleod clutches.
