Overview:

Holley's new GM Muscle Series accessories are the latest expansion to our officially licensed GM product line. These die-cast aluminum valve covers and air cleaner kits were designed to have a no-frills, modern style with prominent raised GM "Chevrolet and Bowtie" logos. Intended as an alternative to the existing GM ZZ6 accessories, Holley's GM Muscle Series dress up accessories can be the perfect addition to your engine bay if you are searching for a subtly custom variation from the OEM options. All GM Muscle Series accessories are available in four custom finishes: natural cast, polished, satin black, and factory orange (all finishes have machined "Chevrolet and Bowtie" logos aside from polished version). The Small Block Chevy center bolt valve covers (designed to fit Vortec/ZZ4/ZZ5/ZZ6) feature a generous internal height for exceptional valve train clearance and include pre-installed internal baffling, polished mounting hardware, and oil fill / PCV grommets (valve cover gaskets not included).

Features:

  • Features clean, modern styling with high definition “Chevrolet and Bowtie” logo
  • Specifically designed for GM ZZ6 engines, but will fit all Small Block Chevy applications with center bolt style cylinder heads (Vortec, ZZ4, ZZ5, ZZ6) – polished mounting hardware included
  • Die-cast aluminum construction ensures high detail and reduces the opportunity for warping of the valve cover flange and oil leaks
  • Emissions compliant valve covers include pre-installed internal oil baffles as well as an oil fill plug and PCV grommet
  • Offered in four unique finishes to fit your style: natural cast aluminum with machined logo (ready for custom paint), polished, satin black with machined logo, and factory orange with machined logo

Nice cotton summer shorts with a touch of linen
Color: Coffee, Size: Medium, Color: Coffee, Size: Medium
These are a nice addition to my summer short wardrobe. They add a different look and texture than most of my shorts that are cotton. The addition of linen adds a nice texture to them and you can tell they are visibly unique. I ordered these in a medium and I think they are true to size. The have an elastic top instead of a button/zipper. I'm o.k. with it and they are nice to just throw on. I'm not a fan of the string around the waist. My first picture has it hanging down and I quickly removed it...not needed with the elastic band holding up the shorts. I guess it could be a fashion statement if you wanted it to be. The shorts are very light weight and I can see using them in the hotter months that are approaching. Price point is great!

Comfortable shorts!
Color: Black, Size: Large
I ordered these because I wanted some lightweight comfortable shorts for the summer that were now gym shorts. These are very comfortable shorts. Lightweight cotton material that is not stretchy and it breathes well. The size fits exactly as expected according to the measurements. They also have an elastic waistband with drawstring, but also have a button and zipper, which I found odd, but don’t hate. These shorts have two big pockets in the front, large enough for keys and a cell phone. Deep enough to put your entire hand in. The single back pocket is perfect sized for a wallet, and it has a button that secures the pocket, so no losing the wallet in the movie theater or restaurant. The color is a true black, which I’m sure will fade in the future after many washes, but for now, it is dark and black, not like some that look more navy blue than black. The stitching is also done well. These are probably my new favorite pair of shorts that are comfy able enough to wear around the house when just lounging, but also nice enough to wear out to dinner. Well worth the price, will probably buy another pair in a different color soon.

Top-tier quality and fit
Color: Khaki, Size: Large
I'm really impressed with the fit of this shirt it’s true to size and has a great slim-fit cut. The embroidery and fabric quality are excellent, making it look much more expensive than it is. Perfect for any occasion where you want to stand out.
