I bought a engine from Mark and during the Break in it started to lose oil pressure , so I called Mark and we tried a couple of things to check the oil pressure at that point Mark sad let me Build you a another motor and he did within two days I had a motor that ran perfect . Mark ended up pulling the motor apart with the bad oil pressure and it end up being the oil pump was Faulty from the factory . I will do business with Mark again he’s a man of his Word and builds a nice motor . Thanks Mark

After spinning a bearing in my V 10 excursion I realized I needed a total rebuild.I found Mark squires on Facebook And gave him a call he said bring it in. he looked at it gave me a price and said it would be ready in seven days. four days later he calls me and said the truck was ready to be picked up. After picking it up I had an oil pressure issue. I called Mark and he said to bring it back by. After finding a faulty oil pump Mark replaced the pump. He had the truck back to me in two days. Mark is no nonsense and straight forward. If you’re looking for a quality stock rebuild, he’s your man. Mark gave me an extremely fair price and completed the job sooner than was stated and totally backed his work. Engine runs strong and I’m very satisfied. I highly recommend Him. Henry H
