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.

It does exactly what they say it does! Worth the money
Color: A1-Red
It arrived quickly. It’s a fun toy! It’s the right size for cats. Definitely worth the money. It is exactly as described. So far, the quality seems very good and it seems durable. The instructions are on the side of the box, which makes learning how to operate it easy. I love it that it’s red, because my kitty seems to be attracted to red. My kitty is very interested in it, yet isn’t quite sure what to think of it. I love that it changes directions on its own so that it doesn’t get stuck or lost under furniture, which is typical for a ball that cats play with. It seems to only go two, three or four feet in one direction and then it changes directions, which is both good and bad. I just wish it would go farther in one direction before changing directions so that my kitty could chase it farther, as we have plenty of space in our house for her to run. But that certainly could be a plus for other cats, enjoying not knowing where the ball is going to go next and really keep them on their toes.

Cat loves this
Color: A1-Red
This toy is great for keeping pets entertained. The ball moves quickly and the tail makes it even more fun for cats to chase. It’s rechargeable and easy to use, and my pet stayed interested much longer than with regular toys.

Really cool cat toy for even the most picky cat!
Color: A1-Red, Color: A1-Red
I love it, wow. Our cat is picky with toys, but even he was intrigued by it. It really kept his attention, which is hard to do. It comes with three modes: fast, slow, and interactive. The only thing is that hair can get all trapped up in it because it's a wheel, so keep your house clean I guess lol. The tail also came off once, so you gotta snuggly get it on up there. Really cool cat toy though, I'm happy I got it lol

Not worth the money
Color: A1-Red
My small Chihuahua loved this toy. It kept him entertained until it would stop working. He only gets about 10 minutes of play and it's no longer charged to use. I even bought a second one thinking the first one might have been just bad luck, but nope, the same problem. It seems most of these interactive toys are only given 2 to 3 stars. I'm disappointed but more importantly, my pup is even more.

Terrific product
Color: A1-Red
I adopted a 2 year old cat - she’s not much for a lot of the toys I have purchased for her, until this one! At first she seemed very cautious with it - but still followed it around - once I slowed it down (a few different options) she loves to play with it! Great purchase very pleased with it
