You’re sure to 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, 1995 and earlier heads. The Avenger’s self-tuning capabilities 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 range while maintaining excellent mid-range torque as well. Avenger Stealth Ram systems include: intake manifold, billet throttle body, ECU, wiring harness, fuel rails, 36 lb/hr injectors, fuel pump and related small parts. Ranges up to 500 HP! Set up is done on the included hand-held tuner so no laptop is required!

All Avenger EFI systems come with all installation components including wiring harness, sensors and in-line pump. Return fuel line to tank is not included.

These kits require the use of a small diameter distributor, such as a small cap GM HEI or most MSD distributors. A large cap GM HEI will not fit with these kits.
