About Zinn Engine & Machine
Zinn Engine & Machine is a great machine shop that built performance engines. Customers say the shop has immense knowledge and attention to detail. It is a go‑to place for any engine work, with no job too big or too small. Many have had SBC engines machined and have had Harley Twin Cam 88 bored out to 95. Turn‑around is quick, often less than a week. The shop can remove axle bearings and hubs from 60‑year‑old cars in little time. Inventory is off the chain and the shop is the place to go for restoring older classics. When equipment needed a lathe, he listened, measured twice, and milled to the new specs in under two days, at a reasonable price. Customers recommend the shop for its skilled craftsmanship and great service.

I brought in a Yamaha warrior 350 head with two snapped off exhaust studs and they drilled and put inserts in the holes at a very reasonable price and in a timely manner. Very happy with the work they did.

Great machine shop! They've built a couple of performance engines for me, and I've always been impressed with their immense knowledge and attention to detail. It's my go-to place for any engine work. No job too big or too small.

Great work and very impressive turn around. There is nobody local in sierra vista and very few in Tucson that will touch Harley Davidson Machining....
