Bad Ass Cars

Welcome to Bad Ass Cars! Your source for free performance car & engine tech tips, how-to videos, photo galleries, information and entertainment for all gear heads and enthusiasts. 

"That's Bad Ass!" It's 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.


Hello hot rodders and power addicts, welcome to Bad Ass Cars! My name is Arron Johnson. I'm retired now, but I spent over 30 years of my life building all kinds of 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 help prevent you from making costly mistakes that I learned to avoid along the way by offering my free Tech Tips and How-To videos section at this link.

All of the cars and/or engines in the slide show above I built, and it's only a tiny fraction of them.


I built a reputation for building some of the baddest, most powerful - reliable, and best performing street and race engines and cars across the nation and around the globe. A lot of the cars I built in my day ended up in many major magazines, including numerous cover shots and multi-page articles and have won countless local and national car shows. 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 clients in all 50 states and 14 countries around the world.
