Devious Customs

Worst experience I’ve ever had with a shop ! The complete lack of communication and after-sales support is unacceptable. I would strongly caution anyone considering purchasing from this company, if something goes wrong, you should not expect any help. the owner Jeff doesn’t know how to talk to customers at all gave me attitude the whole time.

I purchased the LS conversion kit for my Lincoln Continental from Devious, and it’s been nothing but problems since. The kit arrived with the wrong sump pan, and the fuel pump in the tank failed right from new. Both myself and the shop doing the install have tried countless times over several months to contact Devious for help or clarification, but we’ve received absolutely no response. The lack of communication and after-sales support has been extremely disappointing. I would strongly caution anyone considering buying from this company — if something goes wrong, you’re completely on your own.

The LS swap kit they sold me was completely wrong nothing lined up, not even close. It was so off, I ended up tossing the whole thing. Might’ve had better luck bolting it on with duct tape and wishful thinking. Also worth noting—Jeff Davy clearly has an attitude problem, and thanks to him, I’ll be taking my business elsewhere. If I wanted to be treated like an inconvenience, I’d go stand in line at the DMV.

Walked in with a request for some custom work and was greeted respectfully. This place is super busy doing custom everything, so the fact my work was taken and finished promptly was a pleasant surprise. Thank you Jeff

We bought a full LS conversion kit plus other parts for a 62 Lincoln convertible we are working on at our shop, Farland Classic Restoration, in Englewood Colorado. The kit is extremely well-made and we were able to have the engine mounted in the car in a very short amount of time. It's saved us extensive fabrication and design work. Last week we purchased a special radiator and some other parts from them. Very good people to work with. Highly recommended.
