-10% Avenger Stealth Ram EFI Kit, Small Block Chevy, Vortec Heads, Polished

You’ll get some attention when you pop the hood and show an Avenger Stealth Ram™ Multi-Port EFI system! Available for traditional or Vortec headed SB Chevys. Simply utilize a laptop (or the optional 5.7” full color touch screen LCD) along with the HP’s self-tuning capabilities to make it as easy as 1, 2, 3 to get your car up and running with EFI. The tunnel ram design of the Stealth Ram™ builds power in the upper RPM while maintaining excellent mid-range torque as well.

HP Stealth Ram™ systems include: intake manifold, billet throttle body, ECU, wiring harness, fuel rails and related small parts. Fuel pump and injectors should be selected separately to fit your requirements.

Holley Avenger EFI systems are equipped with 4 programmable inputs and 4 programmable outputs that are ideal for most vehicles with a single power adder. This feature allows the user to configure the system to support a wide range of controls including boost control, progressive nitrous, water/meth injection, speed inputs, fuel pump control, AC inputs, timing retard inputs and various other uses. When selecting an ECU, users need to ensure their planned controls can be run with the 4 inputs and 4 outputs as certain combinations may use more I/Os than are available. If more I/Os are required, users should choose the Dominator VMS.
