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

Great value
This suit was the cutest for my son’s graduation. He is slim enough to fit a 5 but tall enough for a 6. I did get size 5, it fit good, except the vest was a bit on the smaller side. Luckily my boy is skinny. The quality is great. Definitely get your moneys worth. The only con I have is that this item was definitely worn before & likely returned to Amazon. The shirt was wrinkled and not packaged like a “new item”. It was in a regular plastic. You can see in the photo the wrinkles on the shirt sleeves.

Nice suit
This 5 piece set is really nice Pros: fits true to sz which allows it to sit nicely The pants have adjustable waist bands The color is as described Material/fabric is not that great but will do (select a neutral color which can prevent it from looking cheap) Perfect for a growing boy who will need another one soon Cons: The tie is little short and is a non adjustable elastic the handkerchief/pocket square does not fit in the faux pocket. If you want an elevated look - wear with a different tie, thicker fabric white shirt and nice shoes

This suit had me questioning whether the manufacturer had ever actually seen a human child before. The pants were SO long — like they were tailored for a 9-year-old with 100 feet of shin. 😂 I had to hem them significantly just to make them wearable for a normal boy. The bow tie was also a letdown. Ours may have arrived defective, but it only seemed to have one hook with nowhere for it to actually attach, so we ended up improvising with the fabric loop. Not exactly the polished wedding-ready moment I was hoping for. The shirt was probably the highlight. It has a subtle textured pattern that makes it feel a little more unique than a standard dress shirt, which I appreciated. Unfortunately, the fabric itself is stiff and not particularly comfortable. Overall, the whole set feels pretty cheap quality-wise. BUT… he’s 9. He’ll outgrow it before the next wedding invitation hits the mailbox anyway. 😂 For one day of looking like a dashing young gentleman instead of a tiny tornado in sweatpants, it got the job done. Just definitely not something I’d recommend for peak summer wedding season unless your child enjoys marinating in polyester.

Pretty good fit on my son. I'd say it's true to size. He looked great for his guitar recital.
