First time using this shop for a 7.3L powerstroke diesel no complaints full machine job was done in a descent time frame and delivered almost on time which is a huge frustration i have had with many other engine shops I have used. More importantly the tolerances were perfect the components were the cleanest I have ever got back from a shop and price reasonable for the scale of work done 5 stars I will definitely return here next project! Highly recommended.

Jenkins performance is an experienced engine Engineer with a great team. I have been to Jenkins twice after Russo Performance Blown my cylinder heads twice because of too much timing. Nothing worng with bottom end, so back to Jenkins to get it done properly and find a new tuner 👍 …

James has built a few engines for more over the years including a nice 434 n/a sbf which is his most recent build for me. Stout enough and reliable for track and street duties to put in a full bodied falcon to run a pb of a 9.90 1/4 mile time. His work is second to none. He takes great pride in his work. And I highly recommend Jenkins performance engines to anyone. 5 stars all the way
