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

Great for Kids, Smells Nice, and No Harsh Chemicals
Size: 5 Ounce (Pack of 2)
This sunscreen spray is easy to apply, not greasy, and doesn’t leave a sticky residue. The tropical fruit scent is light and pleasant, which makes it easier to convince kids to wear it. I also like that Alba Botanica avoids oxybenzone and other harsh chemicals. It holds up well for swimming and outdoor play. The 2-pack is convenient to keep one at home and one in the beach bag. It is a great deal!

Does not spray
Size: 5 Ounce (Pack of 2)
Does not spray!!! This is the second set I purchased and I have had issues that I was unable to spray with 3 of the 4 bottles. Was incredibly inconvenient when we brought a new bottle on vacation and it didn't work. Company would not send a replacement - only a physical coupon. I cannot find the sunscreen in stores and the coupon only covers about half a new bottle.
