What we do
Engine machine services
We are a dedicated automotive machine shop. Everything we do is engine work — for cars, light and large trucks, diesel, industrial equipment, farm tractors and motorcycles.
Cylinder Boring
Precision boring to restore true, round cylinders and correct wear before your rebuild.
Cylinder Sleeving
Save a cracked or scored block with a properly fitted sleeve instead of replacing it.
Stroker Block Machining
Clearance and machine work for stroker rotating assemblies and custom builds.
Line Boring & Honing
Main bore alignment and honing so your crank spins straight and bearings live longer.
Block & Head Surfacing
Flat, clean deck and head surfaces for a gasket seal that holds under real load.
Diesel & Heavy Duty
Machining for diesel truck, industrial, farm tractor and motorcycle engines.

FAQ
Common questions
Still have a question about your engine? Give us a call — we're happy to talk it through.
What kinds of engines do you machine?
Automotive, light and large truck, diesel, industrial, farm tractor and motorcycle engines. We are a machine shop — we do engine machine work only, not oil changes, tires or general repair.
Do you guarantee your machine work?
Yes. All machine work is guaranteed to your satisfaction. If something isn't right, we make it right.
How long have you been in business?
We opened our doors on January 1, 2016 and bring over 10 years of hands-on engine machining experience to every job.
Can you save a block that another shop said was scrap?
Often, yes. Sleeving, line boring and surfacing can bring a worn or damaged block back into spec. Bring it by and we'll give you an honest assessment.
How fast do you respond?
Calling is the fastest way to reach us. If we're on a machine and miss your call, we return it within 2 hours during business hours.
Do you work with shops and businesses, not just individuals?
Yes — we machine for homeowners and DIY builders, repair shops, fleets, businesses and tractor companies.
