Kevin, Sammy and Eric go above and beyond on getting work done in a timely manner. Craftsmanship is second to none…Chris Moore
One of the very best machine shops around ….and some of the best guys in the business. …Sammy Tompkins & The Kevin Mullins are great guys …. known them both for almost 20 years now …. they know what they are doing ……I recommend this shop to a lot of people ……Brian Alford
“THE” Kevin Mullins doesn’t just mean one Kevin Mullins, it means that this is “THE” ONLY engine builder you should be using! TKM and Demon Performance are rocking the modern HEMI world!!!Nathan Ferrell
These are some of the best guys and gals to work with they have an awesome shop filled with the most state of the art machines and the turn around on my big block Chevy motor aka (dump truck motor) lol was great I’ve beat the brakes off this motor and it’s still running strong #TTFMFS. #GOLDDIGGERMUDRACING.Gary Chesney
