HO300-121 - DUAL CARB INTAKE LS1 LS2 LS6

Suit Dual 4150 EFI 4BBL 1000cfm Throttle Body

Part Number: HO300-121

FEATURES:
The Holley GM LS1/LS2/LS6 2x4V dual-plane was designed in the tradition of the great dual Holley 4160 induction systems that competed on drag strips, in Trans-Am and at Lemans in the 1960’s. The technology of the LS pushrod engine is now mated with the impressive multi-carb looks and performance of the muscle-car era
The dual-plane equal-distribution layout produces great mid-range torque without compromising top end power. The LS engine architecture does not utilize an intake mounted water neck or \distributor so it’s perfect for two Holley carburetors and this intake manifold desighn takes full advantage of that opportunity
Carbureted and EFI versions available
Power band from 1500-7000 rpm
Appropriate for any street/performance, muscle car, or street rod enthusiast
Cast aluminum construction
Intended for use on all GM LS Gen III engines equipped with LS1/LS2 style cathedral port cylinder heads
Carb Flange Center-To-Center: 8-5/8”

love!
Color: Black, Size: 2+1 Tier Size, Color: Black, Size: 2+1 Tier Size
these floating shelves are sooo cute and i love them so much. it took a HOT minute to put them together (prob like 30-45 mins for me), but i can’t explain how happy i am to have them! i hung these once in my last apartment and re-hung again after moving, and they’re still great. the only con is that the rail around the bottom shelf (the part “holding” the L block, plant, and white block in) is a little bent and i can’t straighten it out no matter what i do. it’s really hard to tell, but it’s not quite level with the board beneath it (pic 2). i’m just a perfectionist so it was very clear to me when putting it together haha. nobody else notices it until i point it out, and i’ve begun to overlook it too, but just a little something that i wanted to add.

Perfection in a corner!
Color: Brown, Color: Brown
They're gorgeous and easy to mount. Hands down, highly recommend. They look really high quality and feel that way, too. They fit my corners perfectly, and have a really rich color to them. I'd absolutely buy them again.

Beautiful space friendly
Color: Brown, Color: Brown
Absolutely love these three piece shelves, they were perfect for where I wanted them to be placed. They give that corner such a great look. I love that they can be used face up or down. The color I chose is exactly as described and made of real wood thick and slightly heavy., easy to install perfect for any corner especially when space is limited. Would absolutely buy another set!
