XFI™ EFI FOR YOUR SMALL BLOCK CHEVROLET

Almost since they were first introduced, Small Block Chevrolet engines have been legendary for producing great power in a compact, affordable engine. Option codes like L79, Z28, and LT1 conjure up images of high-winding Small Blocks turning in impressive quarter mile times. Over fifty years later, Small Block Chevy motors are still going strong, and with the advent of the easy to install and tune XFI™ multi port fuel injection from FAST™, a new breed of mouse motor is raising the bar for drivability, reliability, and performance.

Easy To Install, Easy To Run
Designed as a stand alone Electronic Fuel Injection (EFI) system, the XFI™ EFI system uses a fully user-programmable Engine Control Unit (ECU) and clearly labeled wiring harness that are surprisingly easy to install, a snap to tune with any laptop or desktop computer, and capable of performance that will blow your mind and make you want to sell your entire collection of carburetors. The FAST™ XFI™ system precisely balances fuel, air and spark to produce  awesome power and superb drivability. Plus, it allows you to fine-tune like never before using C-Com™, the XFI™ system’s easy-to-navigate software. With the infinitely tunable, race-ready XFI™ system, you no longer have to live with flat spots in your horsepower curve, or settle for a “close enough” tune.

Flexible Horsepower –Only From FAST™
Aggressive camshaft profiles, high compression, and all other horsepower-increasing modifications are no problem for the XFI™ ECU. From mild to wild, the XFI™ EFI system delivers a level of flexibility and dependability that is virtually unheard of with obsolete carbureted systems. With your EFI-ready intake of choice and one of our 4150 or Dominator style 4-barrel throttle bodies, you can build any level of performance -from boulevard cruiser to dragstrip dominator. A sixteen-injector unit that can supply enough fuel to support over 4,600 normally aspirated horsepower is even available for ultra-high horsepower race engines that can’t get enough fuel with a mere eight fuel injectors.
