Overview:

The Holley GM LS3/L92 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 LS3/L92 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 product
Color: Purple, Color: Purple
My dogs loved these toys. Durable and apparently very coveted as my puppers “argued” over who got each one. Kept them playing and chewing for hours. Giving only 4 stars instead because I Wish the size was bigger because I have found that sometimes I don’t see it and stepping on it is Absolutely NO FUN.

Rottweiler approved
Color: Purple
My Rottweiler puppies love these bones. I feel good about letting them play with these and not worry they will break or that they can choke because they are durable and a good size and weight. I like the variety and can put peanut butter on the crevices if I want to give as a treat. Worth the money!

FOR SHORT TIME USE
Size: X-Small, Color: Ring Bone
My puppies love this. After a couple of weeks, it is worn so I throw it out and buy another since it's reasonably priced. I don't want them to actually ingest a chunk of this.

Great for our puppy
Size: X-Small, Color: Ring Bone
This chew toy has quickly become our puppy’s absolute favorite. She’s just starting to teethe, and keeping her busy and comfortable has definitely been a challenge, but this ring has been a lifesaver. She was interested in it right away and keeps coming back to it on her own, which is a huge win. The chicken flavor seems to really hold her attention, and it gives her something appropriate to chew instead of everything else. It’s the perfect size for a very young puppy and easy for her to hold and gnaw on without getting frustrated. It keeps her occupied, helps soothe her gums, and gives us a much-needed break during those teething moments. If you have a puppy just starting the teething phase and need something safe, durable, and engaging, this is an excellent choice and one I’d happily buy again.
