  • We have had great dealings with S&J over the years. They always go above and beyond to take care of us and our customers. They've even helped us with warranty issues for customers on engines that our customer bought from other companies that had gone belly up because their name was involved. Can't thank them enough for their ongoing customer support!

    • Shea H.
  • We have bought multiple engines from S&J and they have all been amazing. Hands down the best running/idling engines we have purchased for our customers vehicles. They have competitive pricing and the best warranty we have come across. They're so good and so busy that sometimes we have had to wait for an engine to be built but that is a small concern for the quality of their engines. The staff are great they always answer any questions. If I could I would only use them to supply engines for our customers.

  • I rarely leave reviews, but I felt compelled to do so here. I received an AMC 242 for my 2000 Jeep Cherokee Sport, and it's a phenomenal engine. Everything was great, from the gasket kit, to the break in oil, to the shipping container (half pallet, enclosed in cardboard.) Engine is running great with no issues. They were great as a company, and worked with me to suit my needs each time it was necessary. I don't plan on buying an engine again anytime soon, but I wouldn't buy one anywhere else. Two years later and the engine is still running like a champ with no issues. It's been through extreme heat and extreme cold. Super happy with S&J.

    • Craig C.
  • My experience with S&J Engines was phenomenal! I spoke with their representative Scott who helped me through the entire process of acquiring a S&J remanufactured engine for my 1974 American Motors Javelin. I was very impressed with the videos of the complete remanufacturing process that S&J has posted on their website, but I was even more impressed once the remanufactured 232 ci, 6 cylinder engine arrived. It was amazing how precisely it was put together and ready for reassembly into my car. There it NO WAY I could have reproduced the same quality engine by myself or using another party to rebuild my stock engine. A remanufactured engine from S&J was certainly the way to go. I look forward to many enjoyable hours of dependable driving in my AMC Javelin for years to come. Thanks Scott and everyone at S&J who was involved in the remanufacturing process and delivery of my "new" engine.

  • I searched nationwide finding someone that would work WITH me on my 300 six cylinder build. I had given up and was going to rebuild mine myself. It’s been 35 years since last build so wasn’t excited about that. Found these guys by mistake. Super grateful I did! To say they work with you is an understatement.

    • Ron F.
  • Ryan came through when all else failed. Seriously, I attempted to get my engine picked up for service and almost a month into waiting, I reached out one more time and Ryan got right back to me. Within 2 days my engine was picked up. My faith in people was restored after my experience with Ryan. Here’s hoping the remaining experience goes as smooth. Thanks again Ryan

  • I needed to replace the long block on my 1980 Jeep CJ7. My son told me he had purchased a long block from S&J years ago, with no trouble with it to this day. I spoke to Dennis when I called....lucky for me ! He knows what he is doing...I don't. But he handled the calls with confidence in the product he was selling and gave me all info on warranties available to me. He never made me feel bad for asking so many questions. He was professional but not pushy, he was very pleasant, like talking to a friend. He told me how long S&J had been in business and their success rate. I trust all the info I was given and glad that my experience was good. It is never fun to be faced with replacing an engine on a vehicle but I am confident that it will go well. Thanks Dennis and S&J engine ! I'm glad that my son referred me and I will be happy to refer someone if they find themselves needed to replace an engine. LRF... Palestine,TX

My machine shop was truely impressed with the engine. Said it was way better that what you get from O'Reillys. Also so impressed with the break in oil they are going to start using it in their shop. They were quick to deliver the engine as well. Cost a couple hundred more than most, but worth it So far, running like a champ. For what it is worth, I haven't had a problem yet. Very happy about the whole thing.

QUALITY

NEW COMPONENTS - NOT REUSED. S&J employs more new parts than the competition. This is well known, but why do we continue to buck the trend towards reusing "reconditioned" parts? Because we know you are looking for the engine that will simply last, year in and year out. Through the sweltering summers and the most frigid of winters, without fail. Engines that resist corrosion in marine environments, that increase in power and in tractability as break-in times are fulfilled. Powering your pickup? You'll need that reliable torque. Melting the asphalt with your custom build? You'll appreciate that trouble-free horsepower being ladled out. Restoring or resurrecting that beloved dream ride? We can help you make everything correct and picture perfect. And we'll do it by providing you with the finest remanufactured engine available.
