Small Block Chevrolet - Gen III/IV - LSA

If you're looking to swap an LSA or LS engine into your vehicle but your engine didn't come with an alternator bracket or the factory setup is too wide to fit your project, Holley has the answer. The 20-166 Bracket tucks the Alternator in closer toward the engine when compared to the original LSA accessories, giving more clearance where needed. These brackets look truly at home on the LSA engine, so much so that nobody will realize it didn't come from factory this way.

NOTES: Torque M10 bolt to 36 ft./lbs. When wiring the alternator, install the included 197-400 plug into the alternator. Next, connect the yellow wire to switched voltage that is "on" when the key is in the run position. If the vehicle has a "charge indicator light", the yellow wire can be connected to that circuit.

  • Compatible with the original LSA damper/pulley and similar aftermarket versions

Great for Sun Allergy Rashes!
Scent: Unscented, Scent: Unscented
I have an autoimmune disease called Sjogren’s Disease. With that, for me, comes a sensitivity to the sun in the form of sun allergy rashes. Also with that, I did a deep dive on the best sunscreens and read a lot of reviews on here. I put some of the outer sides of elbows where my sun allergy rashes were when I received it. There was slight sting, but the skin there was already slightly broken. I really love the texture of it, how it feels on my skin and that there's no white cast. It’s moisturizing, too, with no greasiness. Absorbed really well.

The best mineral sunscreen
Scent: Unscented
I’m so impressed by this sunscreen! I’ve been using mineral sunscreens for years and this blows every other one I’ve tried out of the water. It is silky smooth and applies so easily, absorbs well and doesn’t feel greasy or heavy. It doesn’t leave a white cast but it still protects very well! Of course like any sunscreen it’s only as effective as your usage, so reapplying is paramount. The unscented truly has no smell to it, which is something I appreciate. Using it for the first time, neither myself or my fair kiddos got sunburnt. It’s just all around a fantastic, clean mineral sunscreen and will be my go to from now on!

Wellness Staple for Sensitive Skin
Scent: Pear & Coconut Water, Scent: Pear & Coconut Water
I’m becoming much more intentional about the products I use on and around my body, especially while traveling, and this sunscreen ended up being one of the best things we packed for our girls trip to Mexico. My friend has extremely sensitive skin and typically reacts to a lot of sunscreens, so we wanted something mineral-based, reef safe, and more wellness-conscious overall. We split one bottle between the two of us over about five days, and honestly it held up really well. It felt lightweight for a mineral sunscreen, blended in better than expected, and didn’t leave our skin feeling greasy or irritated in the heat. Most importantly, neither of us experienced sensitivity issues or breakouts during the trip. I also appreciated the peace of mind of using something reef safe while spending so much time in the ocean. It’s one of those products that aligns well with a more mindful, health-focused lifestyle without sacrificing effectiveness.

Love the scent
Scent: Tropical Breeze
This sunscreen has such a great scent and is easy to apply with no white cast. Skin doesn't feel clogged or sweaty. Easy to apply and distribute. Like that it's a zinc oxide sunscreen that is doesn't leave a white cast and has a wonderful tropical scent. Wish it came in SPF 50 or higher.
