"Had my engine machined by Kurt, and to this day its still running strong with no issues. I have a pedal to the medal attitude with every on ramp. Drive it like you stole it. Not one issue. These guys know what they are doing. I wouldn't suggest anyone else. They define the word professional. I live in las vegas now, and when I get ready to build another engine, I'm driving the miles to get back to main machine. Btw, did I mention I have over 45,000 miles on my engine? Yeah, quality over quantity."

"This shop is absolutely incredible at what they do!!! Have been using them for years. Never had one issue that couldn't be resolved. If you need service that they provide, they are the best in their class."

"Great customer service the guys were super cool. Highly recommend."

"I had my 91 5.0 rebuilt here in 2011, with a special high torque cam, GT40P heads, and special 9.5 compression ratio so I could run regular gas. That engine now has 6100 miles on it and has seen lots of off road driving and freeway miles. Still awesome, runs great allows my Early Bronco to get 14 mpg doing 65 on freeway. Highly recommended."
