The worst machine shop I've had the misfortune of dealing with, personally and professionally. Issues: Poor workmanship and quality, incomplete work, low levels of professionalism or professional courtesy, billing for work not performed, and lastly doing unauthorized work. I have had numerous awful experiences both personal and professional with this machine shop. They come highly recommended over the years so I expected at least a 4/5 star service and workman ship to be top notch. They have been in the business for a long time, so you expect a shop like theirs to have it down to a process. Personal: I had my engine built for my track car a shop on the other side of town, I was excited to see the shop I had selected using Ball. I got the engine completely overbuilt, got it on the Dyno for the tune, and my very experienced tuner noticed a noise that caused him to cut off the session and advise me to get it towed back to the shop. Turns out Ball Engine had clearanced my engine wrong, requiring my shop to spend the time to take the motor out and replace Cams, Crank, And all valves and retainers. Another 2 months of my car being down, and she's back. Finally everything seems right. 7K miles later, my engine in my track car snapped a valve on track. Bucket wasn't spinning. Engine seized. 10 K down the drain, because of their mistake. No warranty. Professional: They also did work for my Dealer. Sent some heads over to be inspected and advise on needed work. My customer was on a tight budget rebuild. Ball engine does 500 dollars of unauthorized work. The heads don't even look cleaned. It's still got a bent valve. Subsequently, Each of our service advisors has at least one "incident" with this machine shop, all having to do with work quality and price. It is apparent that Ball Engine is riding on its laurels of previous work and does not care one bit about its customers. Skip this place and save yourself many headaches. read more

Ball and engine has always machined all my motors and flywheel for many many years and they have done an excellent job. Both Andrew and David Ball are extremely knowledgeable and has been extremely helpful. They always get my specs down to the exact one-tenth of a thousand. This is the machine shop to go to if you have any motor builds, projects or whatever you need done to your engine. read more

My husband brought in a cylinder head with a broken valve, asked to have it fixed, they talked him into a valve job on both heads but he got home and decided he would do everything himself except the cylinder for the valve. They agreed, a week went by and they told him it would be done on Saturday, he went in on Monday to get it and they said they were still waiting for the valve-originally he was told it was in stock. He said "I am taking this to a different machine shop thanks for wasting my time" and the guy said "Back at you" . Once they weren't going to make a lot of money on him they just didn't care, this is actually the third time he has had them do work , the first job had to be taken back, but he continued to be a customer because of the convenience, it is right around the corner from our house and he prefers to use independent businesses. We don't see how his time was wasted all he did was leave my part sitting somewhere, anyway, he has lost a good customer. We found a great shop that had the work done in one day. read more

This place does not even qualify for one star. Poor service and followup on phone calls. My car has been there for 3 months to have work done and I keep getting excuses and still do not have my car back. read more
