"Jack and Todd rebuilt my 2004 Silverado 2500hd. They did an excellent job at a good price. After I got it back it ran great but had a couple of issues. Jack asked me to bring it back to make everything just right. They are very honest, easy to work with and absolutely honor the warranty"

"Spoke to the owners. Super knowledgeable and ready to go. Be prepared for a bit of a wait, but when you're good sometimes there's a line,right?"

"Had him build me a chevy 350 with a blown head gasket. When I got it back from it had 2 blown head gaskets. He won't admit he messed up because he don't make mistakes. He told me he would cover it but when done he charged me for the new head gaskets anyway and now I'm out a warranty that's probably useless anyway. He uses the cheapest parts and he very unprofessional *Update. Motor WAS installed professionally and all parts were new, jack still blamed all other equipment. Jack is unreliable and untrustworthy, As soon as I saw bubbles in the radiator I told Jack, heat tabs were still in place. His response was to take out the thermostat and see what happens, probably just air he said. I finally took the motor back after the heat tabs melted. I have many other complaints this is just by far the worst.. Motor has since been built by a professional and truck drives amazing"

"Would recommend this Business to anyone looking to replace an engine! Quality Work, Great Customer Service,.. Any Miscommunication I had with Jack was quickly resolved accordingly! Received my Rebuilt 350 for my C10 & Am Fully Satisfied & will Be Back For Additional Business! Thanks Gentlemen, Jack’s Son Worked On My Motor & Went Above & Beyond When I Needed Some Extra Work!!!"

"Fantastic product and customer service!! We had Jack and his team build a 350 small block Chevy for our 1965 Chevelle. Engine sounds and runs amazing. Jack was very patient with all of our questions and concerns. The price and delivery time were fantastic as well. Would highly recommend using Engine Exchange and Machine!!"
