I would like to share my experience with J & M Engines. Jeff took the time to drive to our home in the mountains, diagnosed the problem with our 1999 Dodge 2500. He lined up a shop to pull the engine and reinstall the engine. Wrote up a quote and went above and beyond to keep the price he quoted us. Jeff tore down the engine, machined necessary components and rebuilt the entire engine with all new parts. He then took the time to deliver the truck when the job was completed. The truck is running great and saved us from having to purchase a new truck. I called a number of shops to get pricing on rebuilding the engine and didnt even get a call back. I would highly recommend J&M Engines to anyone. Very professional and they do excellent work! I would rate them the highest rating possible.

Jeef did a fantastic work rebuilding the engine on my 67 C10, He is super nice person, very profesional, I highly recommend him, Juan V.

Jeff with J&M Engines rebuilt my 454 engine for my 70 Chevelle. Jeff is both knowledgeable and personable and I enjoyed working with him through the build process. Jeff does not take shortcuts and I was impressed with how meticulous he is in everything he does. We fired up the engine last weekend and I’m so happy with the performance. Jeff came to my home for initial start up to make sure the engine was tuned and timed properly. I’ve used other engine builders in the Denver metro area and none of them even come close to the build I received from J&M.

Dropped off my engine to have it inspected and dipped and have my crank shaved. About 2 weeks later I paid 200 for the crank work. A month later the engine still hadnt been dipped so I just went ahead and picked it up with the crank but the crank I picked up hadnt had any work done to it.

Jeff is a super nice guy and did some great work. Thanks again!

Awesome service an good on price
