Overview:

The Holley LS1/2/6 Lo-Ram intake manifold kits are designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads. These intake manifolds will work with OE or aftermarket cylinder heads. The Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine applications and the 105 mm throttle body part number 112-581 or similar models. The base intake manifold is designed with a low height to aid the packaging of a plenum mounted air-to-water intercooler in a top-feed configuration. The 300-620 top-feed plenum entry configuration is designed to allow the included Hi-Ram 105 mm plenum top to be fitted to a low-profile base intake manifold. The short runner, low-profile base intake manifold intended for forced induction applications was conceived to package with an air to water plenum mounted intercooler with a shorter overall height than possible with other existing intake manifolds. The fuel rail kits come with two sets of brackets. A set for long (usually standard length) fuel injectors and a set for short (such as Pico, or LS7) fuel injectors.

Features:

  • Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads
  • Designed for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm depending on the application. With forced-induction and the short runner length the engine rpm at which peak power occurs is more likely to
  • Modular design allowing the use of the included top-feed plenum entry
  • Low height to aid the packaging of a plenum mounted air-to-water intercooler in a top-feed configuration or to fit under a stock or mildly modified hood in the front-feed configuration
  • High volume fuel rails and mounting hardware included with ¾”-16 o-ring ports (8 AN)

Borderline Fraud: A Profound Waste of Money
Size: 11, Color: A-black
The shoe pictured and the shoe delivered may as well be from another planet. Pictured is a fairly nice, well constructed shoe made of what appears to be leather or a high quality leather substitute. Delivered was a flimsy shoe made of plasticky vinyl with a sole constructed of grainy rubber blocks individually and sloppily glued without care to the bottom of the shoe, also vinyl with an eight of an inch of the same grainy rubber coating it, offering no solidity or support. Having been worn a total of one day, the majority of which was spent seated at a desk, the vinyl has already crumpled into unattractive wrinkles and creases that resemble nothing so much as a cheap vinyl table covering wadded up and stretched back out. Taking the shoes off resulted in both insoles clinging to my socks and coming fully out of the shoe. I would also mention that the shoe runs large, but I that would indicate that you should use my experience as a buying guide, when nothing could be further from the case. Buy these shoes only if you enjoy being ripped off, pouring money down the drain, or perhaps if you are looking for a gift for a person you despise. Outside of these possibilities, I advise you to run, far and immediately. You certainly won't be able to run anywhere with these on.

Go Tour Men’s Premium Leather Loufer: Excellent
Size: 11.5, Color: A-dark Brown
I bought this for my husband for his birthday. He Loves it ! Well made, very comfortable and he loves the feature where the back of the loafer folds down and can be worn around the house as a slipper. Leather quality is topnotch. He said he would buy it again and highly recommends it ! Thickness is just right ! Ease of use A+ Traction A+. Support A+

Very comfy and a really nice shoe—one flaw, but I still recommend it.
Size: 11.5, Color: Black Grainy
These shoes are nice, comfortable, with a sleek, leather-like insole that allows your foot to move well. The only thing they could have done better is extend the sole slightly farther at the tip. As it is, the lower front part of the shoe tends to scrape against the pavement, causing scuffs. It’s nothing that can’t be managed with shoe cream, but over time, the abrasion may cause more serious damage. That said, for the price, this is a nice shoe and should easily last at least a year.
