Mark went through a set of Ford FE heads for me. Valve job, valve guides, hardened seats, and converted from umbrella to positive seals. Very fast, very high quality work. This is one of the most competent automotive machine shops in the region. With that said, Mark is no-nonsense, and hes going to do it the right way no matter what. So be prepared to just listen...hard for most to do these days...especially racers. I wish I could freeze this shop in time forever. Shops like this built America.

Its all in the details! Meticulous and Precision are two that come to mind each time I step into their shop! Motorcycles and ATVs need to know this is the shop for your top-end rebuild!!

Mark machined and rebuilt my 327 sbc. I was looking for a reliable “hot street” setup (oxymoron right?). He advised me on cam selection and pistons. This engine has never missed a beat. I have driven the car cross-country in the Hotrod power tour. I always have confidence the motor will get me where I want to go. Exactly what I was looking for.

I have been taking machine work to Mark since 1972. I have been involved in this industry for my entire life. I have served as a technician in many shops, served as a heavy equipment tech, and have also served a long stint as service manager at some heavy truck garages. For the last 30 years or longer I have operated my own shop and parts store.For all of these years I have trusted Mark with the same confidence that my customers also expect of me. I can offer them the finest quality work and advice because that is what Mark has always delivered. At times I was forced by circumstance to try other machine shops. None have ever delivered the stability and reliability of D.A. Clem Automotive. I dont have any reason to call anyone else. Mark runs a full service facility, and our facility relies upon him multiple times every week. Hes kind, attentive, and personal. These are qualities I admire and respect. My hat is off to you Mark!

Only place Ive found in Wichita that can bore a motorcycle cylinder. Fair price and very quick turnaround.

Extremely poor customer service. As stated by others, I just got lectured. Old guy on the phone had an attitude. He was not even give me an estimate over the phone.. not even a price per hour. Will not do business with him ever. I am even confused on how it has three stars, surprised it doesnt have less.

Great work..

Run down shop, had high hopes for quality work as he was referred to me by a bigger machine shop I normally use. He didnt approve of my use, or need to run billet forged parts in my motor. Flat out asked me Do you know anything about building a engine? you know nothing. I was there to have him bore my block, and grind my crank down. He refused my service because he didnt like how I was building MY engine with MY money. I was there to have him do the machine work, NOT build my engine. I wont refer anybody to this guy myself, PLENTY of shops in Wichita, and neighboring states that will do this kind of work. I was just, and STILL shocked how he treated me. Glad I didnt leave my parts there to be done. Avoid this shop, and go elsewhere!

This man does exceptional work. He balanced my 383 Stroker Motor about 18 years ago. I was very impressed with his articulation and meticulous attention to detail.

Great service. Great work. I have had a lot of machine work done there always top notch. Great service also.

All he does is turn down easy jobs.

Poor customer service. I just wanted a cylinder hone service and got lectured. all he had to say is yes or no. This is 2018 not 1949.

This guy knows his stuff.

Top notch machine shop

Says doesnt do BMW engines and cant turn a heat treated crank. Fact is...BMW cranks are heat treated. They are forged. And plenty of BMW cranks have been turned and ran for a long time.
