HO300-122 - EFI HI-RAM LS1-2-6, w/92MM T/B

Suit Single GM LS 92mm Throttle Body

Part Number: HO300-122

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 aluminium 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.

Love it, nice for tough chewers, split in half during play
Size: X-Large, Color: Textured Ring, Size: X-Large, Color: Textured Ring
LOVE THIS PRODUCT, would’ve gotten 5 stars but i threw it for my dog and it split in half on contact with the floor. It had lasted us well over 5 months, it’s not his favorite toy but he’ll pick it sometimes, i wouldn’t say it’s unsafe in half just don’t give the smaller parts!

these incredible aggressive chew toys – they've seriously been a game-changer for my pups! I know it's a bit late, but better late than never, right? I've got a couple of power chewers at home, a Rottweiler and a Labrador, and anyone with big dogs knows the struggle of finding toys that actually last. These bad boys have been in constant rotation for over a year now, and I'm genuinely impressed by their resilience. They're incredibly tough! Funnily enough, we originally had three, but now we're down to just one. The others aren't broken, though – I'm pretty sure my dogs just loved them so much they've hidden them away in some secret stash, as they tend to do with their favorite treasures! Beyond just being durable, these toys have been a massive help with their training. They’re fantastic for redirecting all that enthusiastic chewing away from my furniture and shoes, which, let's be honest, is a huge win for any pet parent! Considering how long they've held up to some serious chomping, the price point is absolutely spot on. You definitely get great value for your money.watch your toe they are heavy. If you've got a dog that's a champion chewer, you absolutely need to try these out. They're a lifesaver!
