Remanufactured, NOT rebuilt. And yes there is a difference, a big difference. Unlike many of the products out there, S&J engines are not simply taken apart and rebuilt. They are painstakingly inspected, piece by piece, element by element and each component is given new life. And rather than expect yesterday's equipment to keep up with today's tougher engine tolerances, S&J uses the latest in engine technology, tools, and expertise to transform your engine. S&J continually upgrades its equipment and training to ensure the engines we produce today are equal to or better than the original. When you purchase your engine from S&J Engines you receive the highest quality remanufactured engine available from the most committed engine supplier in existence. When it is possible to do it better, they will.  

In order to activate your engine warranty, S&J Engines, Inc. must receive a completed Warranty Form within sixty (60) days of receipt of purchase.  Failure to complete the verification process renders your warranty null and void.  To view warranty requirements and conditions, click HERE

**Note: sometimes we have engines that are already built / ready to ship that are painted grey.  If the color you select is different, we will include a can of paint in the color you select.

Very Happy
I had them rebuild my 401. I was very happy with the results. His engine builder was very professional and I have had no issues with the motor yet. Only complaint I have is I would have liked to know what size pistons they put in it. Other than that I am very happy. The turn around time was less than 3 weeks from the time my motor left my shop and came back.
