Holley GM LS3/L92 Hi-Ram Intake Manifold with a Terminator X Stealth 4150 2X4 EFI Kit.

Transform your GM LS3 or L92 engine with a Holley GM LS3/L92 Hi-Ram Intake Manifold and Terminator X Stealth 4150 2X4 EFI Kit! These upgrades are perfect for high-performance applications built to dominate the track. They’re made in the USA and come in three finish options: natural and shiny, natural and black, or natural and gold.

The Hi-Ram intake manifold is a cost-effective alternative to fabricated sheet metal. When combined with high-flow LS3/L92-style cylinder heads, this intake offers unbelievable power potential for naturally aspirated or forced induction engines in the 6.0 to 7.0+ liter range (with max power at 7000-8000+RPM). The 6-1/2” runner length and tapered 4.25" to 2.77" cross-section integrate smoothly into a wide range of engine configurations, ensuring a perfect fit on your classic car or truck. This intake’s plenum top uses a 2x4150 square bore mounting configuration and features a lightweight yet durable cast aluminum construction for reliable performance. This intake is only available in a natural finish.

Hi-Ram Intake Features:
- Runner Length – 6.50”, As-Cast Runner Cross-Sectional Area – Tapered 4.25" to 2.77"
- Plenum Top Gasket Type – 3/32” Round O-ring Cord
- Mounting Flange Gasket Type – Standard LS3 Molded O-Ring
- Port Size – 2.49” Height x 1.21” Wide
- Base Plenum Top Mounting Flange Height – 8.42” to the lifter valley cover flange on engine block.
- Height (Carbureted 2x4V Top Mount) – 11.08” to the lifter valley cover flange on engine block.
- 2 X 4150 square bore mounting configuration (sideways or inline mounting)

The Holley Terminator Stealth X EFI system is a bolt-on replacement for your 2x4 4150 flange carburetor. It features eight 100 Lb/Hr injectors that can support up to 1500 HP on Naturally Aspirated applications or 1250 HP on Forced Induction applications. The Terminator Stealth X ECU is incredibly easy to set up, requiring you to only answer a few questions on the hand-held device before the calibration wizard takes over. From this point, it uses fuel map self-learning and ignition timing control to continuously self-tune for the best possible performance. In addition to making the most of your engine power and fuel, this ECU also improves idle stability, drivability, and wide-open throttle horsepower. Best of all, this EFI kit is available in a shiny, black, or gold finish!
