Hello hot rodders and power addicts! My name is Arron Johnson. I'm retired now and NO LONGER BUILD ENGINES, but I spent over 30 years of my life building race winning & show winning cars and engines, and now I want to share my knowledge and experience with you to help get your car performing at its absolute best, and to help prevent you from making any costly mistakes that I learned to avoid along the way by offering my free Tech Tips section to you on this website.

A lot of the cars I built in my day ended up in many major magazines, including numerous cover shots and multi-page articles. They've won countless local and national car shows, and many of the race engines I built went-on to win races around the globe, including setting track records and creating multiple class champions in road racing, drag racing, mud boggers, Baja 500 trucks, Silver State Classic & Bonneville 100 cars, drag boats, and beyond. I built cars and engines for people in all 50 states and 14 countries around the world. 

I built a reputation for building some of the baddest, most powerful - reliable, and best performing street and race engines and performance cars across the nation and around the globe.

"That's Bad Ass!" was the first thing people would say when they saw the cars and engines I built, and that's exactly how my shop got its name.
