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 well
Color: Silver
The stainless steel caddy quality is fine, the sticker was easy to install on the inside of my stainless steel sink. I initially used the small movable arm to hang on the hooks, and it did not keep the caddy in place. Anytime it was hit, it fell off or tilted off the hooks. Customer service followed up with me on my purchase, gave me the correct instructions with a picture, and I was able to snap the caddy into the hooks. They were responsive, listened to my concerns and answered my questions, and now it works great. I would recommend this.

It doesn’t take up so much space
Color: Silver
This is perfect for my use. I did have to place the sticker on it to hold it in place. I have a Blanco sink which isn’t smooth.

Negative reviews are misleading it definitely works just fine.
Color: Silver
Noticed the only negative reviews were because the hooks would not fit and was sort of concerned about that, but I figured it might be one of those things where it’s the person’s fault not the product. Sure enough it was. The hook fits, yea you have to push it in there with a slight bit of force, but it definitely does fit. What those people don’t realize is that by design the hooks are like that to keep a firm hold onto the tray itself. I found it funny how mad people were about that when really it’s very very simple to make it work. Nice product sticks well, seems sturdy.

Good product, lousy instructions
Color: Silver, Color: Silver
This is a good product with terrible instructions. I’ve used this adhesive strip before so I know how to install the basket & how to remove the strip. To get a snug fit position one of the basket's vertical wires in the middle of one of the horizontal bars then press down hard until you hear it snap into place, it’s now snug & will not tip over. To remove the adhesive strip I used a putty knife & wiggled it underneath the strip until I had loosened & lifted enough of it to get a good grip & pull the rest off. Mine is installed on a ceramic tile back splash not in the sink so this method did not damage the tile, can't say what it would do to stainless steel. I'm a 72 y/o woman with arthritis, if I can get the adhesive off anyone can.

Works well, but very difficult to remove!
Color: Silver
Perspective: Ive had this caddy for 3 years and it has suited me well. Over time the hooks that hold the caddy in place loosened and the caddy would occasionally fall off the side of the sink wall. Not a huge deal, just a small inconvenience. Over time it started to happen more often because the plastic hooks completely lost their grip so I decided to replace it. Well it literally took me 3 days to get it off of the side of my sink. Using different tools to jimmy it off because the adhesive is sooo strong (which is a good thing, until you are looking to remove it). It took a razor blade and several bouts of goo gone to get the whole thing off as well as the leftover adhesive. The fact that it lasted for 3 years is a testament that it is a good product, but it lost several stars for the drama and pain and suffering it took to remove. I wont be buying another one.
