While Littleton Speed Garage owner John Neff started in the LSX world in 2014, with his first full engine builds and tuning started in 2015, he has been into cars his whole life.

First doing tunes for swaps into older muscle cars and trucks, Neff grew LSG to focus on more performance builds with cams, heads, injectors, turbos.

Offering consultations on things as simple as wheel/tire sizes, all the way through designing a project engine build front to back, Neff prides himself in meeting every project head-on.

“I enjoy working with each customer to build an individual plan for their vehicle. My passion is customizing vehicles and optimizing engines…. and helping people go fast.”
