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.

Very nice look
Size: 13 Wide, Color: Brown
Very nice look, sole is comfortable, inside upper leather is a bit stiff. Not enough to hurt but not soft. I would purchase another color.

Nice shoes but no half sizes.
Size: 11, Color: Brown
I had to return the shoes because they do not have half sizes. Other shoes i always wear an 11. That was tight with these and 12 would be to big.

Perfect casual Friday shoe with great comfort and style
Size: 10, Color: Optic White/Egret
These have quickly become my go-to shoes for casual Fridays at work. The fit is true to size, and they’re both comfortable and stylish without trying too hard. They pair really well with jeans or khakis, so they’re easy to dress up or down depending on the day.
