Welcome to the next level of Small Block horsepower!

Ever since the first 265 CID engine rolled off the assembly line in 1955, Small Block Chevrolet engines have been known for their versatility, compact size, and light weight. Since then, Small Block Chevy engines –also known as “mouse” motors, have delivered superb street, track, and marine performance for everything from solid-axle Corvettes to river running jet boats.

The EFI experts at FAST™ have a wide variety of components to help you build the injected mouse motor of your dreams. Whether your goal is to retrofit a bone stock TBI small block into your street rod or off road vehicle using one of our Perfect Circuit™ OEM-configuration wiring harnesses, or to run a screaming, 16-injector big-inch stoker using our race-winning XFI™ standalone EFI system, Fuel Air Spark Technology™ has the technical assistance and products that can make it happen!
