Holley LS EFI Manifold - 2x4 Dual Plane LS3/L92 - Black 300-134BK

The Holley GM 2x4 dual plane manifold is designed in the tradition of the great dual Holley 4160 induction systems that competed on drag strips, in Trans-Am at Lemans in the 1960's. The technology of the LS pushrod engine is now mated with the impressive multi-carb looks and performance of the muscle car era!

• Power band from 1500-7000rpm
• Perfect for any street/performance, muscle car or street rod enthusiast
• Cast aluminum construction, Black Ceramic Coated
• Fits all GM LS Gen III or Gen IV engines equipped with LS3/L92 style rectangular port cylinder heads.
• Dual plane design for equal distribution and great mid-range torque without comprimising top-end power

The LS engine architecture does not utilize an intake mounted water neck or distributor. NOTE: The EFI versions of the LS HI-Ram intake manifold and fuel rail are designed to accept Bosch Style EV-1 or Magneti Marelli Pico fuel injectors. OE LS fuel injectors may not fit properly in the Hi-Ram EFI intake manifold fuel rail assembly. There is a kit available separately for the LS7 Hi-Ram EFI to allow the use of stock LS7 fuel injectors, P/N 300-230 (see below in the service parts section).
