The Events

Holley LS Fest is a celebration of everything and anything powered by the incredible GM LS engine! If an LS based or current generation LT engine is powering your ride or if you are considering a swap to LS power, this is your event! Race cars, street rods, rat rods, muscle cars, trucks, late models – you name it, if it is being powered by an LS there will be something here for you! Take part in our drag racing classes, autocross, 3S Challenge, burnout challenge, off-road challenge, Show-N-Shine, and more!

Our New and Hot LS Products

New Holley Mid-Mount LS Accessory Drive!

Holley Mid-Mount Complete Accessory Systems pull all the accessories for your GM LS engine in tighter than ordinary accessory drives for a clean, compact look. At the heart of it is the revolutionary “bracketless” design (patent pending), where all accessories attach directly off the water pump for an integrated look that shows off your horsepower – not your accessories.

Hooker LS Cast Iron Turbo Manifolds

Holley’s new LS Turbo Exhaust Manifolds are made from cast iron and allow a simpler and easier way to add a turbo to your muscle car. These manifolds are made from High-Silicon-Moly ductile iron and are much more durable & retain more heat than fabricated headers. The manifolds kits include v-band clamps & flanges, heater hose heat shield, and header bolts. A turbo cross-over tube is used to connect the two manifolds (sold separately).
