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 manifold and rail kits will work with OE (Original Equipment) or aftermarket cylinder heads. The 300-624(satin) & 300-624BK(black) top-feed intake manifold kit provides two injectors per cylinder for hi-volume fuel demands, flexible fuel supply strategies, and dual-fuel capability. The top-feed, short runner, low-profile base intake manifold was conceived to package plenum mounted intercoolers for high-boost turbocharged or supercharged induction systems with a shorter overall height not possible with other existing intake manifolds. The plenum top is configured to be fitted with 105 mm throttle body part number 112-581 or similar models. The dual fuel injector 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. Available in satin and black finishes. Holley Lo-Ram intake manifold kits include all the sealing o-rings, plugs, and fasteners required for the installation of the kit.

Features:

  • Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads
  • Provides best performance for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm, depending on the application
  • Dual-injector, separate-passage, high-volume fuel rails with mounting hardware, dual-fuel capable, 8 AN o-ring ports
  • 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
  • Available with both as-cast satin and black power-coat finishes

They stand out, and are flashy, but sizing is complicated.
Size: 34, Color: Black With White Strip, Size: 34, Color: Black With White Strip
High-quality pants and flashy. The stripe adds a lot of attention for reasons both good and bad. The materials they were made are excellent quality. Pants are thick, but not too thick, and are lightweight, guaranteeing easy movement. Comfortable - could wear these all day. I do love their appearance. They made me feel like a million bucks. :) The only problem is sizing and fit. I normally wear size 34 for waist in jeans and dress pants like these, but the 34 I got didn't fit at all - too tight. So, I ordered a 36, and it fit, but barely. When I sat down, there was too much tightness in my "masculine area". I also ordered a 38, and, well, they were just too big - practically hung off me. A 37 would probably work for me in these, but they don't offer such a size. I have to return the 34 and 38. Will keep the 36, see if I can have it altered in some way. Length was fine. Being 1.86 meters, often the length in these pants is a little on the short side. In the photo, I'm wearing size 36 and the black pair with the gold stripe, which is actually more of a flashy yellow. I liked how I looked in them, but they were a little too tight at times, the belt wasn't even necessary. It enhanced the outfit though, don't you think.

Good as a standard "Tuxedo" pants
Size: 42, Color: Black With Red Strip
Red Striping could be wider. These are good as a standard "Tuxedo" pants but if you are looking more fore a "Security Guard" style pants the striping needs to be wider.

Runs small in the waist
Size: 34, Color: Black With Black Strip
These are good pants, but as other reviewers have noted, they tend to run small. Order one size up from the size you normally order. I'm a 34 inch waist, and I ordered the 34. They were tight, and I had to have them let out. I may order another pair, and if so, I'll order the 36. Don't be vain. Be smart.

Good value
Size: 40, Color: Black With Black Strip
My husband and brother in law both found these pants to fit a little smaller than regular dress pants.....mostly they were tighter in the thighs but the length/waist was perfect. They each ordered a size or two up and had the pants tailors to fit. They looked very sharp and were of a good quality considering they were not super expensive. I hope they have the chance to wear these more often!
