I dropped my 4bt Cummins off there in August 2020 for block and head work. I stopped in several times to check the status. He told me "he knows where the engine is". Im not sure what that means. Extremely disappointing. I will be picking the engine up and taking it to someone else, that is if he still has it.. He's had my Pontiac 455 for over 20 years.. I dont know why he's like this... I think he's at the neighbors all the time jaw jacking and never gets things done...
John and Terry were very helpful, I brought in a snowmobile cranck case with a bolt that the head broke off of, I tried to get it out myself but I couldn't, john got it done in just a couple hrs and did a spectacular job! I highly Recommend this machine shop, they have a lot of knowledge and experience, and are easy to deal with.
Ended up abandoning my engine there. Dropped off a GM 2.4L Twin Cam engine and a $700 set of pistons for cylinder boring, decking/surfacing and some valve work. I was working on building the engine for boost. The engine was dropped off in April of 2025.
Great place for all engines I brought a dirtbike jug in and needed it honed. Took maybe 2 hours and did an amazing job
