Overview:

The Holley GM LS7 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 LS7 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.

Works as it should
Size: 24 inch 100Hz
I started a new job a few months ago and I get to work from home one day a week. They do not pay for you to set up a home office however, so I was looking for a cheap monitor for part of my set up. I came across this one and decided to try it out. I work in client service for a finance company so a lot of what I use it for is email, other conversational programs, and then our custodian software. I’m not doing anything crazy. I have it connected to a name brand laptop and it was very easy to set up with no issues. It turned right on. The picture quality is nice. Again, I’m not doing editing or anything on this so it works for what I need. It does NOT have speakers, so I do need to use the speakers on my laptop( which can be annoying), but again it’s not a deal breaker. I have been using it now for 5 months and it’s been working really well for my set up. I am thinking of getting a second monitor and I would get another of these but also I do want a speaker so I don’t know that I would get this exact version. For the price, if you are looking for something basic for normal work from home needs, this does the trick!
