Have had Cal work on a few Subaru blocks of mine as well as a few small valve train things here and there for a friend. He’s always been fair priced, friendly, and does good work! Or at least my purring engines think so.

Small one man shop he has machined atleast 6 sets of heads for me, I have never had a quality issue or timeliness issue. Hard working shop!

Cal is the guy you want doing your machine work. He is extremely knowledgeable and meticulous and hus prices are more than reasonable.

Cal is very knowledgeable and great to work with, he got my engine done quickly, I will be back for other projects.

Great service, speedy work great price, very knowledgeable engine specialist

I get all my machine work done by cal, awesome guy and first class service

Great work, fast, friendly, reasonably priced. Cal knows what he is doing.

Cal really knows what he is doing ! this is the place to bring your engine block ) cylinder heads to in the greater Billings area. trust that your project will be done in a professional and timely manor.

Getting head resurfaced and he was very welcoming and professional.

Needed someone to advise me on whether a Subaru block i had could be bored out. He did a preliminary test and decided it was irreparable. He called me right back a few hours later and told me the news and didnt charge me for his advice. Thanks.

Cal for years has delivered above and beyond, when he retires many shops will be hating life as his work is top notch!

Got parts done right and quickly
