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”

Size: 28W x 34L, Color: Medium Indigo
My 16-y/o 6' grandson wears the 28"-34". Not easy to find. These fit him well. Material is regular blue jean. Good value

Nice jeans, but too tight in the thighs
Size: 31W x 28L, Color: Light Wash
I liked these jeans overall — good quality and the stretch feels nice — but they were a little too tight in the thighs for me. If you’ve got more athletic legs, you might want to size up or try a different fit.

Same sizes but different fits
Color: Light Green-new, Size: 32W x 32L
Great color and good fit. Feels more like a Jean. I bought two pair-exact same size. 32w x 32 length. Light green was exactly what I wanted. The maroon red was more like a jegging than jeans. Not what I wanted. Supposedly same style - so just be aware fits were completely different!
