HO300-123BK - EFI HI-RAM LS1-2-6 MANIFOLD

Suit Single GM LS 102mm Throttle Bod

Part Number: HO300-123BK

The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!
The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.
Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations
EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.
Cast aluminum construction.
Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.

Great bottle opener
Size: One Size, Style: Bottle Opener
Love this bottle opener. Looks and feels just like the screwdriver. Easy to grip just like the hand tools. Good gift idea for the electrician or a diy person that appreciates quality tools.

Great bottle opener and looks cool too
Size: One Size, Style: Bottle Opener
Love this opener. Matches with all the other screwdrivers in my tool box and have it ready to whip open a beer whenever needed. Slips into the pocket to carry with you as well. Solid tool and I gave a couple buddies one as a gift. These will see many years of beer opening super fast.

Funny yet good bottle opener
Size: One Size, Style: Bottle Opener
Nice rubber grip. It would be better if the metal part was one inch longer, but still very functional.

The right tool for the job.
Size: One Size, Style: Bottle Opener, Size: One Size, Style: Bottle Opener
This is the tool you want. It is exceptionally functional, well made (made in the USA, if that matters to you), and beautiful in the way that quality tools are. The thing that really sets this tool apart is that it correctly balances form vs. function: a heavy duty build (as is the point when buying a bottle opener built by a tool company) without its use as a bottle opener (as is the point when buying ANY bottle opener) being negatively impacted by said build. I also bought the Craftsman bottle cap wrench, which, in my opinion, is hugely successful as feeling like a heavy duty tool and something of a failure as a bottle opener. It's so large and heavy, it has equal mass to the bottle you're opening. Imagine your buddy who has had one too many wielding a 12 oz. steel wrench over your tile floor, countertop, toes, etc. and you'll get the idea. Lastly, the engraving and materials on this Klein tool are so attractive I had to build it a custom wall mount instead of hiding it away in a drawer or tool chest. I will be buying a second for the office.
