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

Amazing Men Watch
Color: black watch 76
I recently purchased the Olev men's watch, and I’m very impressed with its quality and design. The watch looks elegant on the wrist and feels durable, with a comfortable fit for daily wear. The timekeeping is accurate, and the materials feel premium for the price. It’s perfect for both casual and formal occasions. I would definitely recommend this watch to anyone looking for a stylish and reliable accessory.

A nice daily watch
Color: red watch for men 76
This watch does look good in person, however, I bought it an extremely discounted price. The band is the same generally accepted, plastic-like band you will find in less expensive watches but it's bright color makes it stand out. The mini dials on the watch face do not move, so I personally would not pay over $100 for any similar watch. (It's original asking price was near 3x's that). I'm happy with it, which is why I still gave it 4 stars. At a low price, I would buy this in other colors to match my outfits.

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.
