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

Not pleased- No holes predrilled in wood!
Love the look of it and should have been a good review BUT there were absolutely no holes drilled and a total of 64 screws to put in. So I have 2 slabs of solid wood and the pipes. I could have purchased and made it myself if it doesn’t even come with pre drilled holes in the wood. Have to get someone to drill all the holes for me and hope the can line them up properly before I can put together. Hope it works as returning this large and heavy of an item would be difficult. Very disappointed in what should have been a great item.

Nice for storing canned/ bottled drinks
Material Type: Three Tiers Cart
Great. Wish I could've gotten it in a darker brown color, but it serves it's purpose.
