By popular demand, Holley is expanding the draw-thru supercharger carburetor line to now include the XP series. Like the existing HP line, these are available in 600, 750, and 950 CFM flow rates and standard polished with black accents. The feature-laden XP includes a contoured venturi inlet for balanced air flow, screw in air bleeds for precision tuning capabilities, high flow billet metering blocks, billet base plate, and Dominator style fuel bowls which allow plumbing from either side. Supercharger XP carburetors also have a unique capability that allows their power valves to reference the intake manifold vacuum below the supercharger. This allows the power valve to operate as it should, based off intake manifold vacuum. A power valve provides further enrichment to the main metering system under load (low vacuum) conditions. Holley XP carburetors are the standard for square bore race carburetors. Race-Ready out of the box!
Features:
- Tumble polished shiny finish for good looks
- Chevrolet small block 2x4, 671 blower calibration
- Contoured venturri inlet offers balanced airflow for increased horsepower
- Screw in air bleeds for precision tuning capabilities
- Dual 50cc accelerator pumps for additional fuel under initial acceleration
- Dual feed fuel inlets for constant high volume fuel delivery
- 4 corner idle allows you to precisely control your idle system
- Mechanical Secondaries for perfect off the line launches
- Boost referenced power valve for proper enrichment under acceleration
- Throttle lever cut off for clearance on a sideways application
- 100% wet-flow tested by Holley technicians to assure it arrives ready to run!

Super Comfortable and Durable – My Dog Loves It!
Size: 24''L x 18''W x 1.5''Th, Color: Pink
I recently purchased the Mora Pets Dog Crate Pad for my dog, and I couldn’t be happier. The pad is thick, plush, and provides excellent support—my dog curls up on it instantly and seems extra cozy. The material feels soft but also durable enough to withstand daily use, and it cleans easily when needed.
I also appreciate that it fits perfectly in my dog’s crate without sliding around. The non-slip bottom keeps it in place, and the size options make it easy to choose the right fit. Overall, it’s a high-quality bed at a very reasonable price. My dog literally refuses to leave it once he’s on there! Highly recommend for anyone looking to upgrade their dog’s crate or kennel comfort.

Good Quality, Nicely Padded, Durable
Size: 36''L x 23''W x 1.5''Th, Color: Grey
I bought this to put on my couch for 2 cats to sleep on. They are senior ladies and occasionally have accidents. The mat is soft and comfortable for them. Washes like a dream. Very well made, durable, comfortable and protects my couch.

Soft and Perfect for Small Pets
Size: 22''L x 13''W x 1.5''Th, Color: Blue
This little bed mat is super soft and cozy, and my cat took to it right away. The size is perfect for a crate or just laying around the house, and the star design is really cute. I like that it has an anti-slip bottom so it stays in place, and it’s easy to throw in the wash when it needs cleaning. It’s lightweight but still has enough cushion for small dogs or cats to nap comfortably. A great value for a simple, comfy pet bed.
