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

- Original Equipment look ? Available in Natural and Black Finishes

FAQs
|Q. What is an Intermediate Brake Line?
