Holley Hi–Ram Intake for Cathedral Port LS1 LS6 and Rectangle Port LS7 GM Engines
Holley's cast aluminum Modular Hi-Ram™ Intake System is now available for GM LS1/LS2/LS6 cathedral port engines and GM LS7 engines. The new Stock Eliminator COPO Camaro by Chevrolet runs a 427-cubic inch LS7 with this same Hi-Ram intake on the naturally aspirated versions.
The Hi-Ram modular intake was originally introduced for LS3/L92 rectangle port engines as a cost effective alternative to fabricated sheet-metal intakes for high-performance applications where induction system height is not limited. The modular design makes the new LS1/LS2/LS6 and LS7 bases ready to accept a wide range of carbureted and EFI tops and are attractive to builders and fabricators as the foundation for custom induction systems. There are four style tops; for a forward mount throttle body, dual 4150™s, dual 4500™s, and a blank top to machine for any induction style. Billet aluminum flanges are also available for custom fabricated sheet metal tops.For more info and complete list of carbureted and/or EFI tops follow this link:
