When an entire show is based on an engine platform, it's likely there are going to be some wild setups. And every year, Holley LS Fest East doesn't disappoint.

Back in September, we visited Beech Bend Park in Bowling Green, Kentucky, for the 13th edition of the event. The three-day festival brings together LS- and LT-powered vehicles from across the country for a variety of programs and competitions. The only requirement is that participants have a GM LS or LT engine under their hood — it doesn't matter what kind. 

That means the grounds are full of Chevrolet Performance crate engines* (this year the LS376/525* was particularly popular), LS swaps, and both homebuilt and professionally developed race engines. 

Some of the power plants are designed to attract attention with huge blowers and an epic whine, others are subtly featured in restomod builds to provide modern performance, and still others are designed solely to win. 

The engines are found throughout the massive car show, on the drag strip, on the drift track, on the autocross course, and in a variety of surprising places.

Today, we've picked out some of our favorite mills from this year's event to provide you with a taste of engine eye candy. A gallery is below.

*Because of their effect on a vehicle's emissions performance, these engines are intended exclusively for use in competition vehicles. These engines are designed and intended for use in vehicles operated exclusively for competition: in racing or organized competition on courses separate from public streets or highways. Installation or use of these engines on a vehicle operated on public streets or highways is likely to violate U.S., Canadian, and state and provincial laws and regulations related to motor vehicle emissions.
