"TOP NOTCH SERVICE. - All of the staff is easy to deal with, came to them with a goal, came up with a plan, I then changed the plan again... and they were receptive and helped me complete the process. LSx runs like a champ. You get what you pay for and they KNOW what they are doing. After the sale customer support has been great - never left with an un answered question."

"My experience with AES was great from start to finish. The gentleman that answered the phone was very knowledgeable and answered all my questions. I set up an appointment to drop off my engine and finalize my build. It was done in a very timely manner given what was needed to be done and I was very impressed. I was called right away for pick up when it was ready, and even had small chat with one of the engine builders that worked on my engine. Great experience from start to finish I would definitely recommend! Thanks AES you have earned a customer for life!"

"Had an engine built and paid for a matching cam and flowed heads. Never got paperwork verifying or a cam card. Was told they were misplaced and I'd have to figure it out. This information was requested every other weeks for months and then periodically for a couple of years after the build because I kept being told they had them and would send them. Eventually, I was told the records were not retained for that timeframe. In addition, the build took nearly 6 months longer to build than I was originally quoted. I would call weekly for updates, but was clearly being ignored by the builder with limited to no communication as to what was happening or why the build was being pushed out. I'm giving 2 stars because I've finally been able to crank the engine and it's fired and running with limited run time. I will update later on additional results."

"The owner never took responsibility or control of the work his people did on my engine. Had an easy 350 small block increase of HP. After they quoted me $7k to increase HP to 300 0r 325hp, they hit me with another $1,300 to put in a stall convertor, which should have been Included in the intital price. Once they ' installed' said convertor my transmission leaked and didn't stop leaking despite taking it back in o hem to fix TWICE!!!! Now I have to take it to another transmission guy to find THEIR mistake since it didn't leak a drop until their 'specialists' put in said convertor that still does not feel as if any HP has been increased. Trusted and paid them good money that took 6months for a simple rebuild. Never received list and costs of work and parts. For as much as they charged you'd expect a quality product and better customer service. Sadly only mediocre at best."

"Said it would take 2-3 weeks. After 5 months of B.S. and endless excesses I told them I will be coming in for my stuff, and they said it would then be done by the next day. Had to have all the work redone after three races at a much much better shop in Wauconda at 1/4 the price. Now I am at two seasons with no problems. STAY FAR AWAY FROM THIS SHOP."
