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.

Features:

  • Compatible with the original LSA damper/pulley and similar aftermarket versions
  • Compatible with all Holley Alternators
  • Notably more clearance to swap applications than other options
  • Compatible with Holley P/N 20-160 compact SD7 A/C kit
  • Compatible with LSA and 2010-15 LS Camaro water pumps

  • Original Equipment look ? Available in Natural and Black Finishes

Great sunscreen!
Size: 5 Fl Oz (Pack of 2), Style: SPF 50
We love this sunscreen as our compromise between conventional toxic sunscreen and pure zinc that proves challenging to work with! A few bottles lasted us an entire week of vacation!

Easy to Use, Great for Daily Outdoor Use
Size: 5 Fl Oz (Pack of 2), Style: SPF 50
This has become my go-to sunscreen for daily walks. The spray works at any angle, which makes application quick and easy — especially when you’re trying to get out the door. 🙌 The scent is light and summery, not overpowering, which I appreciate. It performs well for regular outdoor use, though like most sprays, it does leave a slightly sticky feel on the skin. For those who pay attention to ingredients, this has an EWG rating of 4 (with 10 being the worst), so while it’s not the cleanest option out there, there are definitely greener alternatives if that’s a priority for you. Overall, a convenient and reliable everyday sunscreen, especially for active outdoor routines.

Only spray I use!
Size: 6 Fl Oz (Pack of 1)
The only spray that keeps mosquitoes away from me. Summers in Georgia are brutal and full of mosquitoes. I miss the old all green bottle though. I think they might have changed the formula.
