Overview:

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.

Good quality and good value for money
Color: 1 Blue and 1 Orange
Love this pickleball paddle set very much because: 1, the quality is great. I’ve purchased two other paddles. The two paddles in this set are satisfied. The feeling of holding them is good and the sound when they hit the pickle balls is satisfying. It’s not heavy, probably due to the honeycomb and carbon fiber material. 2, the colors are pretty and the color patterns are good designed. It’s easy to find our paddles. 3, this set is a good value for money. It contains two paddles, four balls, and a bag. You get everything with good quality with the money for one paddle. Overall, this pickleball paddle set has good quality and good value for money. Worth trying.

Great
Color: 1 Pro White
This new pro-level paddle is an absolute revelation, truly earning its five-star rating. My control instantly improved; dinks became effortless and drops landed precisely where I aimed them. The textured surface generates incredible spin, allowing for shots with wicked curve and dive. Power is readily available, transforming drives into piercing rockets across the court. Even during extended rallies, its balanced feel and quick handling keep me agile at the net. The sweet spot is incredibly generous, providing surprising forgiveness on less-than-perfect contact. It feels remarkably durable, shrugging off aggressive play without a scratch. This paddle doesn't just play well; it feels like a natural extension of my own hand, elevating my entire game. Seriously, if you're looking to upgrade your performance, this is the paddle you need.

I got this pickleball paddle set for my husband and I to try and learn how to play this new popular sport. My first impressions of the rackets are they have a nice, solid feel to them but without feeling heavy. So solid yet lightweight would be an accurate description I think. After playing several rounds with my husband the grip still felt comfortable. Oh and I like the sling bag that comes with it. The bag is big enough to hold all the pickleball essentials. I noticed when we were practicing that the rackets seem to be responsive and easy to control. The rackets are constructed of fiberglass and polypropylene and I have not noticed any issues with them so far everything is intact just like new. It also comes with a few balls to get started. I would compare them to whiffle balls as they are very similar in shape and size. I am happy with my purchase of this outdoor pickleball set. It is a good value for the price, and a good starting point for beginners.
