We specialize in building some of the baddest street and race engines around. Whether it's a stock muscle car engine, a blown & Nitroused Pro-Street engine or an all out ground pounding racing engine, we build 'em! See our engines page for more details.
 

BAD-ASS Racing is located in the heart of the wine country in Sonoma, California, just 10 minutes North of Sears Point Raceway. It's owned and operated by long time hot rodder and racer, Arron Johnson. "My shop is fully equipped to handle most tasks for any street or race car. I deal on a personal level with each of my clients and do my best to provide the highest quality at the lowest price. Give me a call or send me an e-mail... let's talk."

If you're lookin' for strength, quality and serious power for a fair and honest price, you found the right place.

If you're looking for a "cheap" engine, you're in the wrong place.

We didn't get our world wide
"Bad Ass" reputation by building cheap, weak or under-powered engines.
